Upgrade from 5.5.3 to latest version and purchase license

[dungo]

Hi!

We have a Confluence 5.5.3 instaled on a Fedora 20 server with 10 users. The maintenance expired in 2015. It is possible to upgrade to the latest version and purchase a lilcense for 50 users, without changing the server operation system (Redhat Fedora 20)?

Thanks.

Hi! 

I have seen 2 way for solve it:

1. It is possible, but before you need purchase license and set license on Confluence 5.5.3. Then upgrade instance. (Please, remeber your plugins)

2. Or you can set evaluation license and then upgrade, after that purchase license. 

Please, before test you upgrade steps. 

Cheers,
