You may have some work to do but it's really not that painful...
If you want to upgrade from Joomla 2.5 to Joomla 3.x these are the steps to follow:
1. backup backup backup!
2. make sure that you meet the system requirements for J3.x (min php 5.3.10).
3. check that al RT products are on latest versions (gantry, rt extensions and template) update any that aren't and clear server cache and browser cache. Check that RT template you are using is compatible with Joomla 3.x

. You can check all current version numbers in extension manager > manage. Please note if you are using "mission control" admin template that you need to uninstall this by following these special instructions

.
4. check all your third-party extensions are up to date and that they are compatible with J3.x
5. test test test! to make sure anything you updated does still work ok
6. backup backup backup!
7. disable "system - remember me" plugin in extension manager > plugins
8. update to J3.x and clear server and browser cache again.
9. test test test!
10. backup backup backup!
11. re-enable "system - remember me" plugin.
Also, regarding your reasoning for having a dedicated server - I had the same issue with a client site and email - that is why I now use an SMTP service for sending mails
smtp2go.com
- which removes all of that headache of making sure your server doesn't get blacklisted.
