Question

Is it possible to import in Jira 4.4.5. an export made from 4.2.4 ? From 4.4.5 to 6.2.7 I succeded, but as I want to migrate from 4.2.4 to 6.2.7(war distribution), I have to pass thru 4.4.5, so for not use import export DB, I'd prefer to use export import

I enter in 4.2.4, Administration -> Backup Jira data, I put backup as zip.. I chose a name like backup42Test.zip and launch the backup.. than in 4.4.5 with new instalation, instead of customise I choose to import data from backup, and in that moment it says that entities.xml can not be found in my zip file
