Upgrading a Confluence instance from 2.7.2: Issues with plugins and content.

Hi, all

We are trying to upgrade a client's system from Very ancient version of Confluence ( 2.7.2 )

On the system there are lots of plugins that had totally changed in the years.

Hi Tihomar,

Replying to your question:

As far as the database is huge, the question is if there is an automated way for data migration, compatible with an actual plugin version. The key points are tables and calendars.

Sadly nope, the only thing you can do is to upgrade Confluence to it's bridge versions as per this page.

Another advice is to set up a Confluence Test Instance so you can avoid production downtimes during the process, since we are dealing with an ancient version there's no guarantee that everything will run smooth.

Regarding your plugins, my suggestions is that you also run the Compatibility checker prior each bridge version upgrade (I don't know for sure if that is available for version 2.7), since some plugins might be discontinued in Confluence latest versions, like calendars that turned into Team calendars in latest version (your customer will need to pay a license to use it).

Hope it helps,

Thanks and Regards,

Hi Tihomir,

When you upgrade to the each confluence version, you should also upgrade the addons and validate the related wiki content/data is upgraded and functioning. This way you can step through the versions and if necessary pinpoint the version where an issue occurs and remedy it before upgrading to the next version of Confluence and compatible plugins.

Likely, a lot of the addons are still available or the functionality has been wrapped into the core confluence product. As David mentioned, ensure you upgrade in a test environment first so you can evaluate the upgrade process and work out any kinks.

A quick glance through your plugin list only highlights 1 addon from my experience:

Calendar Plugin Plugin Version: 2.6.1

Calendars is not compatible with Confluence 3.5 or newer. You MUST export all calendars in Confluence 3.4.9 if you wish to use them in Confluence 4.x - they may work to some extent in 3.5 but this is not a compatible version with the addon. Confluence 4.x and newer require a paid addon for calendaring - Team Calendars. You can import the .ics calendar exports from 3.4.9 into Team Calendars, but there is no direct migration path. If you upgrade past Confluence 3.4.9 you may not be able to recover the calendars.

Hope this helps.
