Possible Issues when Upgrading

1. Upgrade between the versions 8.0.x8.1.x

After running the upgrade command you may encounter an error:

Error running migrations


In ClassLoader.php line 576:

  Warning: include(<pathtoSuiteCRM8>/vendor/composer/../symfony/maker-bundle/src/Event/Cons
  oleErrorSubscriber.php): failed to open stream: No such file or directory


This issue can be resolved by re-running next command within the SuiteCRM 8 root directory:

composer install

2. Upgrade between the versions

An issue was found on the implementation of the upgrade command between the versions

The issue is that when upgrading SuiteCRM 8 for a second time (i.e if you had upgraded from, then you will have come across the following error after having ran: ./bin/console suitecrm:app:upgrade -t "<version>"

CRITICAL  [php] Fatal Compile Error: require(): Failed opening required '/<pathtoSuiteCRM8>/cache/prod/ContainerZatgzYy/getConsole_ErrorListenerService.php'
["exception" => Symfony\Component\ErrorHandler\Error\FatalError^ { …}]

This issue is a result of Symfony cache clearing but then being called right after.


This issue can be resolved by re-setting permissions and running ./bin/console clear:cache within the SuiteCRM 8 root directory.

You should then be able to navigate to your application.

3. Upgrading to version 8.3.1

There was a bug with version 8.3.1 that caused the upgrade process to fail.

If you are on a version lower than 8.3.0, and you wish to upgrade to version 8.3.1, you will first need to upgrade to 8.3.0 and only after that can you upgrade to 8.3.1.

This issue has been resolved in version 8.4. Thus, if you want to go from 8.2.0 (or any version lower than 8.3.1) to 8.4.0+ you can do it directly.

4. Upgrading from Beta 3 to the RC version

After running the upgrade command in the last step you should get the following error:

Running: clear-symfony-cache
PHP Fatal error:  Interface 'Stringable' not found in /<your-suitecr-8-path>/vendor/symfony/string/AbstractString.php on line 30

Symfony\Component\ErrorHandler\Error\ClassNotFoundError^ {#3095
  #message: """

    Did you forget a "use" statement for another namespace?
  #code: 0
  #file: "./vendor/symfony/console/Helper/Helper.php"
  #line: 63
  trace: {

    ./vendor/symfony/console/Helper/Helper.php:49 { …}

    ./vendor/symfony/console/Application.php:795 { …}
    ./vendor/symfony/http-kernel/EventListener/DebugHandlersListener.php:136 { …}

    ./vendor/symfony/error-handler/ErrorHandler.php:695 { …}
    Symfony\Component\ErrorHandler\ErrorHandler::handleFatalError() {}


To overcome the above error you need to clear symfony cache by running next command on your SuiteCRM 8 instance root:

./bin/console cache:clear
