How to migrate from Alfresco Content Services to Alfresco Community?

[yolanda]

Hello!

We want leaving the paid version and moving to the Community.

Right now we have a very very old version (3.4.14 Enterprise with Oracle as a database) and we want to update as much as possible. From that update (I don't know if it will be 7.0 due to platform support) move to a Community , since the use is only shared storage.

Would this be possible? Has anyone tried? Should we move from Oracle to MySQL?

Any contribution is welcome.

Thank you very much in advance!

The right approach could be:

1) Migrate Oracle DB to Postgres or MySQL (in 3.4.14)

2) Switch to Community version (in 3.4.14)

3) Upgrade Alfresco to 4.1.x

4) Upgrade Alfresco to 5.2.x

5) Upgrade Alfresco to 6.2.x

6) Upgrade Alfresto to 7.2.x

Hi Angel!

The official upgrade path assume direct upgrade from 5.2.x to 7.2. What are the reasons you recommend additional step (5) to upgrade to 6.2.x ?

Thanks,

Serge

You're right, @fedorow 

That intermediate upgrading from 5.2.x to 6.2.x can be skipped.

Hi Serge, 

In general, although it is possible to go directly for small repos, but you may need to pass with Alfresco 6.2 because of Search Services.

Imagine that you have a production service with some millions of documents that require a long reindexing time (for example several weeks). In 5.2, you will use ASS 1.x index, but in 7.2 you can't. So you need to use 6.2 to reuse 1.x index, and then rebuild indices with ASS 2.x for going until 7.2.

Kind regards.

Hello Ángel!

Thank you very much for your answer.

We will try to do it .
I hope  the move from Oracle to MySQL  isn't  too traumatic.

Thank you very much.
