restore to 4.0.8 from 3.3.7

[pmn]

Hello,

Does anyone know whether it is possible to backup from otrs 3.3.7 (using /backup.pl in 3.3.7) and restore to 4.0.8 using /opt/otrs/scripts/restore.pl at one go. I'm getting an error saying 'unknown version'

Thanks.

That won't work. From 3.3 -> 4.0 there were changes on the database. Even if you - by chance - only want to restore data of unchanged columns, I think the backup/restore script checks the version of source and target.

Is it possible to do it manually in mysql?

Probably. But neither would I recommend it, nor do I have any experience with that.

Why don't you restore to a 3.3.7 framework and upgrade?
