Hi guys,

we have a scenario with an old Jackrabbit Version 2.2.5

Is it necessary to rebuild all the Lucene Indexes if we would like to upgrade 
to an up to date Version (at the moment 2.15.4) due the different Lucene 
Upgrades?

Can't help you with the indexing question but please note 2.15.4 is a release from an unstable branch, so you should consider the latest 2.14 version.

Is there a best practise / checklist for upgrading the Jackrabbit Version in 
view of existing Contents / Structures? Do we have to do some kind of data 
changes / preprocessing for the Upgrade Process?

We have different Workspaces and some other restrictions (nodenames > 150 
Chars..), so it is not so easy to upgrade to OAK.

Long node names are not a problem in Oak.

Best regards, Julian
