Enonic version: XP 6.2
I have an old XP install running that I finally have time to upgrade. It is running XP 6.2 and I’m wondering if it would be fine to upgrade directly to 6.6 or if I have to go through all the other versions between the two?
I believe you must go through each upgrade, but this should be confirmed by someone else!
You don’t necessarily need to go through each version, but each version have special upgrade tasks that need to be executed:
6.3: Changes in Mail configuration: http://xp.readthedocs.io/en/6.3/appendix/upgrade/index.html
6.4: Lots of changes in project structure and configuration: http://xp.readthedocs.io/en/6.4/appendix/upgrade/index.html
- Going from 6.2 to 6.4 in the first step is probably a good start. By making a stop on 6.4 and seeing that things work correctly, you can verify that the changes so far, since they are quite extensive.
6.5: Storage location configuration changes: http://xp.readthedocs.io/en/6.5/appendix/upgrade/index.html
6.6: Need to reindex data, and some more configuration changes: http://xp.readthedocs.io/en/6.6/appendix/upgrade/index.html
- Going from 6.4 to 6.6 in one go should also work fine.
As always, if this is a production system, it is good to make a trail update in a test environment before upgrading production.
