1.8.5 to 1.9 upgrade php memory issues

[WT1]

We currently have a database containing almost 275000 testcases in it that we are trying to migrate from 1.8 to 1.9. During the upgrade process, our php memory session limit is being exhausted. I have moved it up to 1024MB and it is still crashing the script after it has exhausted all of this.

Has anyone else see this kind of issue. Any suggestions?

I assume you have increased the memory in php.ini. If so, try to increase the memory for Java in your environment.

We have done both

this mig with this amount of data has been never tested, and I'm afraid will be very, very difficult

[WT1]

That is what we are seeing. That it is very difficult.

You will need to develop using at starting point out migration code, code to make migration on chucks of items to avoid execesive memory usage
