Alfresco migration 224 to 311 : 4 days estimated !

[zomurn]

Hi,

This WE I was supposed to do the installation on the production server.
The process for the migration alfresco 224 to 311 takes too long time to execute !
The prod machine is : windows server 2008 + 30Go RAM + 4CPU Xeon 2.4GHz + on another computer : MSSQLServer 2008 + 20Go RAM + 4CPU 2.2GHz.
The number of document is poorly ~70 000.
The JVM is configured with Xmx8G and Xms5Go
The logs says when I start the application :

At 16% , about 4 days left ! (time estimated).
To reach 16% it was running from saturday 14pm to Sunday 10am … and it was only to 16% !! my god !

Have look at the pics for details :

I really need help to deliver the new version of alfresco to my customer ! I can't let the prod server stopped for days !.

Any help to how accelerate the migration process would be great !

Please contact Alfresco support since this is one of the issues that they are tracking.

I contacted them on the French phone support …. http://s5.parature.com/ics/support/default.asp?deptID=15026
But I'am waiting for them to recall me with a french technical person.

That's surprising because time length for the process is not proportionnal !!
2 months ago, we've done the migration (there was ~40 000 doc) and on a virtual machine (VMware) and it took a short night …. why with 70 000 docs, it takes 8 times more ???
The time length is not proportional to the number of documents in the repository and I was really surprise !
Finally we rolled back to the current version on the production….the migration having been considered as a failure.

Well I just tested on another virtual machine yesterday evening.
The time length was 3Hours to apply the upgrade.
My customer has really a problem with its production server….those final customer…..they would better ask to maintain there network by a computer science engineering company, they need expert !



So the problem doesn't come from the patch.
