Migration/Upgrade of RT to a different VM with a different OS and on a different RT version

Hi everyone,

The company I am working for uses RT 4.2.3 since 2014 on CentOS. We are looking to upgrade RT on ad different operating system (Possibly Ubuntu 20.04/22.04) without losing any tickets.

What would be the best way to approach this migration, please?

Should we migrate RT 4.2.3 to the new OS and then upgrade it to RT 5.x, or is it possible to directly export the database and the configuration of RT 4.2.3 to the new RT 5.x?



You can get a dump of the db:


Then restore the db on the new machine, where you have RT5 installed on. Then you can run the make upgrade command and upgrade the db
