Replication from 4.2x to 5.x version

[icarrara]

I wish to replcate some folders from an Alfresco server version 4.2 to an Alfresco server version 5.x.

It is possible replicate folders between different versions of Alfresco or the two servers have to be at the same version ?

Thank you in advance for some help

Hi Ivanno,

I believe that the TransferService, which is used as part of replication insists by default on having the same edition, major and minor versions for the source and target.  The TransferService has TransferVersionChecker property which is used to determine this - https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/ja...

Interestingly, Alfresco also comes with an alternate TransferVersionChecker called TransferVersionCheckerNoOp.java which allows transfers from any version to any other, but it's not used out of the box.  You could modify the spring configuration of the transferService bean to use this one instead but I don't know what kind of effect that would have or whether it would work properly (or at all).

An alternate option might be to use a tool like TSG's OpenMigrate or something similar, which might allow to you to do this kind of transfer https://www.alfresco.com/partners/solutions/openmigrate - it depends on what your requirements are

Regards
