Alfresco upgrade to 3.4

[metharb_bt]

Hi,

We are running on Alfresco community version 3.0 and planning to upgrade it to Alfresco Enterprise 3.4. We done upgrade on test instance with 2 million documents and it took around 23 hours. On live, we have 10 million documents. Does anyone has an idea to improve the upgrade perforamance?

Is there any way to finish upgrade in 8 hrs?

Thanks,
Rahul Metha

Hi Rahul
Upgradation is simple, about the time, it takes about how much time it takes for the backup.
Following are the steps which I used to follow

At the exsiting server:- 
    Disable indexing in the present system, stop and start stop, 
    Take backup of Alfresco installation DIR
    Take backup of DB

At the new server :- 
   Restore the DB
   Install the new alfresco installation (imp:-do not start the service) 
   copy the alf_dir of the old instance  directory to the new inststallation directory (Please copy only 2 directory named "contentstore"  and  "contentstore.deleted") (Do not copy other directory)
   start the new alfresco instance 
   You have now upgraded the instance without indexing  enable indexing at alfresc-global.properties 
  restart the service 
   You have a upgraded system with solr indexing enabled
