Deprecation and removal of support for CentOS Linux from Claris FileMaker Server
Claris FileMaker Server 19.2.1 is the last version on CentOS and will be supported till October 28, 2022. The next Claris FileMaker Server release will require Ubuntu. We expect this to be released within a few months.
Our MBS FileMaker Plugin already runs fine on Ubuntu servers with pre-release FileMaker Server software. If you’re interested in testing FileMaker Server on Ubuntu, send an email to ets@claris.com to be considered for the External Testing Site (ETS) program. Then you can install a server in a VM and install our current MBS Plugin.
If you have a Linux server, you may just spin up a new one later this year, install Ubuntu and a newer Claris FileMaker version. Then copy your database over and change DNS to point to the new server. Don't try to upgrade. Keep the old server as a backup, ready to take over if the setup of the new one fails. Once you migrated, you can then retire the old server (VM).
In case Claris decides to support Linux on ARM 64-bit in the future, we can would be happy to build our plugin for such a platform.
