Error after importing data from Jira 3.10

[Eric Ring]

After installing Jira 4.0 and trying to import the data from our Jira 3.10 I get this error:

Error importing data: org.apache.commons.lang.exception.NestableException: java.lang.OutOfMemoryError: GC overhead limit exceeded

After getting the error, every part of the new install stops working. I have uninstall and reinstall to try importing the data again.

We are trying to upgrade all the way up to Jira 5.0, but our current install is 3.10. From what I read, I needed to upgrade to 4.0, then 4.5, then I could finally get to 5.0.

Turns out my problem was with my DB Driver not being correct. After installing the correct MySQL Driver everything loaded up with no problems.

Hi Bob,

did you try to start Jira with more memory ?
