Upgrading CrafterCMS

This section details the steps required to upgrade your CrafterCMS install.

Warning

  • This guide assumes that you’re trying to upgrade from a stock 3.1.x or 4.0.x Studio and with some slight Studio configuration changes. If your project/site configuration is heavily customized or your Studio is a custom overlay you might need additional work that is not specified here.

  • The following release versions are able to upgrade to 4.

    • 3.1.9

    • 3.1.12

    • 3.1.13

    • 3.1.17 and later versions

    If you are upgrading from a version other than the ones listed above, you will need to upgrade to one of the above listed supported upgrade paths release version first before upgrading to 4. See the Upgrading CrafterCMS page for 3.1 here: Upgrading CrafterCMS


Verifying the Upgrade

Important

CrafterCMS will attempt to upgrade your project (site), which includes your configuration, code, and other assets. After the upgrade, perform a git diff on your project to see exactly what changed. This will help you identify any undesired upgrades that the system made and revert them if needed.


Upgrade by Installation Type

Here are the instructions for upgrading CrafterCMS based on how it was installed (on a server or via Kubernetes/Docker Compose):

Important

Remember to read the release notes for the version you’re upgrading to and all other release notes in between the version you currently have and the version you are upgrading to, as it contains information on all the changes that have occurred and steps you might have to take when upgrading to a specific version.

Upgrading MongoDB

Note

The following section only applies to Crafter Profile and Social installs.

Crafter Profile and Social version 4.1.0 and later uses MongoDB v6 in the install. When upgrading your 3.1.x install of Crafter Profile and Social to 4.1.0 and later, MongoDB will need to be manually upgraded.

This section describes how to upgrade MongoDB in your Crafter Profile and Social version 3.1.x installed on a server.

Please read through the upgrade instructions here first. The steps for upgrading MongoDB in your Crafter Profile and Social install follows almost exactly the same steps as listed in that document.

Important

Remember to manually shut down and backup CrafterCMS before beginning your upgrades!

Upgrading 3.1.x -> 4.1.x (from MongoDB 3.x)

  1. Download CrafterCMS version 4.1.x, and extract the files.

  2. Run the upgrade-search.sh script from your newly extracted files.

    Run the upgrade-search script
    > ./upgrade-search.sh /path/of/install/to/be/upgraded --stay-alive
========================================================================
Search upgrade started

    See Upgrading Search for more information on upgrading search.

  3. Upgrade using the upgrade-target.sh script from your newly extracted files. First, we’ll need to set MONGODB_HOME so that the backup script will run with the mongod version 3.4.4 in the old installation before running the upgrade-target.sh:

    Set MONGODB_HOME and Run the upgrade-target script from the newly extracted files
    > MONGODB_HOME=/path/of/3.1.x/install/bin/mongodb ./upgrade-target.sh /path/of/install/to/be/upgraded
...
[o] Overwriting file apache-tomcat/LICENSE with the new release version
[o] Overwriting file apache-tomcat/BUILDING.txt with the new release version
========================================================================
Upgrade completed
========================================================================
!!! Please read the release notes and make any necessary manual changes, then run the post upgrade script:

  1. Manually upgrade MongoDB from version 3.4.4 to version 6.0.12. We need to upgrade from each release version and run the setFeatureCompatibilityVersion command against the admin database.

    Please see https://www.mongodb.com/docs/manual/release-notes/6.0-upgrade-standalone/ for more information on upgrading MongoDB.

    Download and extract the following MongoDB versions available from https://www.mongodb.com/try/download/community:

    Run mongod from each release version /extracted/location/of/mongodb-version-to-be-upgraded-to/bin/mongod starting from the oldest one:

    Run mongod from MongoDB version to be upgraded to
    $ /extracted/location/of/mongodb-linux-x86_64-3.6.23/bin/mongod --dbpath=/path/of/3.1.x/install/data/mongodb --directoryperdb --journal --port 27020

    Then login as user admin in mongoDB in your 3.1.x install and set the compatibility version using the command db.adminCommand( { setFeatureCompatibilityVersion: "{version}" } )

    Set compatibility version from /path/of/3.1.x/install/bin/mongodb/bin/
    > ./mongosh mongodb://localhost:27020/admin

Using Mongosh:           1.8.0

admin> db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
{ ok: 1 }
admin>

    Repeat the steps above for all the other versions of MongoDB downloaded in ascending order of version, e.g. run mongod version 4.0.28, then set the feature compatibility version to 4.0. Next run mongod version 4.2.25, then set the feature compatibility version to 4.2, and so on and so forth

  2. Before starting CrafterCMS, you’ll need to configure the installation root directory to use Java version 17. Remember to read the release notes or any relevant upgrade articles and make any necessary manual changes before running the post-upgrade.sh` script as described next

  3. Run the post-upgrade.sh script. This will:

    • Remove old data/indexes-es directory (old indexes are not usable by OpenSearch)

    • Start CrafterCMS and ask for signal to continue

    • Once started and CrafterCMS is up (including UM execution), let the post-upgrade continue by typing Y:

      Please make sure Crafter has started successfully before continuing
> Continue? [(Y)es/(N)o]:

    • Post-upgrade will continue to trigger the reindex of all targets by calling the Deployer API /api/1/target/deploy-all

  4. Your install is now upgraded and you may login to Studio to check the version.

Troubleshooting Upgrade Issues

When upgrading your Studio install fails, the first thing to do is to inspect data from the logs and figure out which statement failed when completing the upgrade. Using the results of the inspection, we then have to recover the database manually.

Failure Executing a Statement

Let’s take a look at an example log:

Failed statement during upgrade
 1Caused by: org.craftercms.studio.api.v2.exception.UpgradeException: Error executing sql script upgrade-3.1.0.6-to-3.1.0.7.sql

Looking at the log above, we can see that the upgrade failed when trying to execute a statement because of a duplicate entry: Error executing: ALTER TABLE `cluster` ADD UNIQUE IF NOT EXISTS `uq_cl_git_remote_name` (`git_remote_name`)

Here, the upgrade failed because of a special case with existing data in a table that needed to be changed as part of the upgrade.

For this case, the solution would be to manually set unique values for the existing rows in the table and then execute the remaining statements in the script.

Upgrade Not Supported

When the system is in an undefined state between two versions, you may see the following message in the logs:

System in an undefined state between two versions
Caused by: org.craftercms.studio.api.v2.exception.UpgradeNotSupportedException: The current database version can't be upgraded
        at org.craftercms.studio.impl.v2.upgrade.operations.DbScriptUpgradeOperation.execute(DbScriptUpgradeOperation.java:105)
        at org.craftercms.studio.impl.v2.upgrade.pipeline.DefaultUpgradePipelineImpl.execute(DefaultUpgradePipelineImpl.java:67)
        at org.craftercms.studio.api.v2.upgrade.UpgradePipeline.execute(UpgradePipeline.java:42)

The above message may occur, if you had an error upgrading because of a failed statement, then you restarted the system again. Because the script was not executed completely, the system is in an undefined state between the two versions. So, the next time the system is restarted, the upgrade will be attempted again resulting in a different message in the logs as seen above. The solution here would be to look some more in the logs for the failed statement before the system was restarted and manually recover, like the previous example.

DB Upgrades Timeout

On start, Crafter Studio will run its Upgrade Manager. When migrating large sites with a large content base, some DB operations can timeout and throw an error like the following:

System in an undefined state between two versions

To prevent the error, the environment variable MARIADB_SOCKET_TIMEOUT in the {Crafter-CMS-install-directory}/bin/crafter-setenv.sh file of the CrafterCMS install you’re running the upgrade script from may need to be increased depending on the size of the existing sites.

Here’s an example of setting the timeout to 10 hours:

{Crafter-CMS-install-directory}/bin/crafter-setenv.sh
# Setting timeout to 10h = 3600 * 10 * 1000ms
export MARIADB_SOCKET_TIMEOUT=${MARIADB_SOCKET_TIMEOUT:="36000000"}
