Upgrade from 5.0 to 6.5: is it supported?

Technical assistance
1

Hi,
i have a (very) old zammad server (5.0.x) and i want to upgrade to last version (if possible).

I installed the last version with no issue and follow the backup and restore procedure to import actual data to the new server but it’s failed with many errors like :

ERROR: duplicate key value violates unique constraint “channels_pkey”
…
ERROR: column “whitelisted_websites” of relation “chats” does not exist
…
ERROR: syntax error at or near “1”

So i guess a made a mistake somewhere.

Is there a way to make this upgrade safely ?

Actual version : 5.0.x
targeted version : latest
OS : Debian

The Update process with such high steps is always from mayor to mayor.
Thus 5.0 to 6.0 anf then to 6.5.

Your errors indicate that you didn’t run the database migrations that are required with every update.

As we don’t know what exactly you executed, it’s hard to help you more specific.

Hi,
thank you for your quick answer.
As a side question, is it possible to download old versions of zammad packages ?

Our instance is running with docker and i think about use system package instead, but i found only sources files. Is there a public repository with old packages ?

Hi @ddelhoume.

You need to check Packages for zammad/zammad.
