T279303 Migrate OTRS CE 6 to Znuny LTS fork (original) (raw)

Migrate OTRS CE 6 to Znuny LTS fork

The Wikimedia Foundation will migrate its instance of OTRS Community Edition 6 to a maintained FOSS fork, Znuny LTS. The patch consists of rebranding, it's graphics and text changes to re-mark the software under its new name. The risk here is low, the migration is expected to go relatively quickly and painlessly.

The migration is scheduled to take place from 07:00-09:00 UTC on 13 April, OTRS/Znuny LTS will be inaccessible to agents during that time. Once complete, agents should be able to log in an resume work as normal. There will be no functional changes to the user interface or experience at this time.

@akosiaris I assume the usual process of emails being held in queue during the migration will occur? My other question, we can assure people that if something happens this is easy to roll back and there's no direct risk of data loss, correct? (naturally there's risk involved in everything, I'm checking our tolerances).

Yes.

Yes, this is easy to rollback. With major version bumps (e.g. 5.x -> 6.x) aside, the upgrade process never really had difficult to revert steps like database schema upgrades.

and there's no direct risk of data loss, correct? (naturally there's risk involved in everything, I'm checking our tolerances).

As you mention, there's always risk. From what I 've seen this upgrade isn't going to touch anything in the database, so I would be very surprised if something like that where to happen, but I can't 100% guarantee 0 data loss.

That being said, we do take backups so total loss is avoidable. If somehow the upgrade manages to irrevocably corrupt the database, we do have the ability to revert to a state a couple of days old.

I am gonna be bold and resolve this as it pertains to the actual migration and that part seems to have gone quite well. I am pretty sure we have a ton of followup work, especially regarding relabelling/rebranding, but let's track all those in their own respective tasks.

Yes, thank you, that's the intention.
