I'd like to import our old JIRA data (412) into our new server (617).
Do we need to install an intermediate 445 first? Or is that only for Jira 3.x upgrades?
If I use the import tool it expects 2 xml files in the .zip file. However the 412 zips only have 1 xml file.
Is the hosted version of JIRA any friendlier in this regard?
