These is a very old, unsupported version. "slightly different versions" 
is unusual. If it is a construct of different servers for frontend and 
backend accessing the same database it might be helpful to upgrade those 
to their newest used version.

Your first step to move to newer versions is to upgrade to 4.5 LTS. 
Having done that you can tackle the upgrade to the current 6.2 LTS.

Take note of the system requirements (PHP, MySQL), you will probably 
need an up-to-date operating system too.

If you have problems with the upgrading process it's better to post 
questions to typo3.german or typo3.english since there are more people 
active there.
