Combine separate Alfresco installations into single multi-tenancy setup - how to do data migration?

[ray_muirhead]

Does anyone have experience or know of the process to convert several existing completely separate Alfresco instances into a single multi-tenacy setup?  Is there a defined process to do the data migration?

In terms of details what we are looking at is:

Existing Alfresco Community 4.2.x each with separate MySQL databases on completely separate servers
Goal is to upgrade to 5.0.d and then condense to a single Alfresco server with data stored in Amazon RDS.

Thanks,
Ray

On each of the server, do you have same content model or each of them are having different content model altogether?

If you are intending to combine multiple servers to a single one then there are couple of things to consider.
1. Users and group migration (it may possible that a same user exists on multiple alfresco server, while moving to a single server, duplication should be avoided. Similarly for Group as well)
2. Migrate the content to a single instance.
Per my understanding, with the earlier version of Alfresco, Alfresco export/import tools can help achieve this. There would be some bit of customization required to it however. You can explore about export/import tools further if you can use them for the recent version of Alfresco.
If you are using enterprise edition, it would be a good idea to contact alfresco support to progress in a step-by-step effective way.

Hope this helps.
