How to convert OC 1.5 Database to OC 2x

Guys i have a quick question,

as you guys know, there are some differences between oc 1.5 database and 2.3 databases...

So lets say i want to upgrade my system from 1.5 to 2.3 how can i also convert or upgrade my DB too?

If you know some MySQL, compare both databases and create/remove required fields. If you don't have enough skills, you can always hire someone to do this for you (me, for example).

This link might be helpful but it's quite long and complex so you may be better of hiring a developer as above or from the Commercial Support forum:
