After moving Jira, I get an error

[Doug Wolfgram]

I built a new VM, installed JIRA from scratch, then archived and copied over the database, the /opt/atlassian/JIRA directory and the /var/atlassion/applicaiton-data/JIRA directory. 

This worked last time I did it. This time, I get these errors the first time I try to access the page... Any idea what I can look to fix? All permissions were preserved when moving the files, but perhaps one got messed up? I am not sure where to look.

Thanks! I had only copied the opt stuff for database config, but the new upgrade (6.4 > 7.1) automatically found and configured my database. I only needed to put the driver jar in lib and voila!

I suspect copying the /opt/atlassian/JIRA directory might have damaged the "installed from scratch" installation.

I would try a fresh install, check that works ok, then restore the database into the target, and copy the home directory again, but NOT the installation.
