We are currently running confluence 3.0.1 in our production environment and are looking to upgrade to Confluence 5.4.
What is the recommended upgrade path? Also, i believe we need to upgrade our license to move from 3.0.1 to later versions. Is this correct?
The recommended path is definitely 3.0.1 to 3.5 first - it can be quite painful to upgrade from anything below 3.5 to 4 and above. You should then test 3.5 to 5.4 - I've done that twice recently, one was plain-sailing, the other made a horrid mess and we ended up doing 3.5 -> 4.2 -> 5.4. It depends on the data and plugins, so I can't tell you a preferred route.
Your licence upgrade isn't an issue, you can just click "upgrade" in your Atlassian account and it'll generate a new one which is valid for 4+.
I would recomend to migrate through latest versions of each major release, did similary myself recently. So 3.0.1 -> 3.5.17 -> 4.3.7 -> 5.4.
But there are a LOT of changes, so try it in test environment before.
If you have valid license maintenance for 5.4 (valid on +- 3 December 2013) you will not have problems with licenses.
