Forum Upgrading to 4.x and a clean start
 

We are thinking about upgrading to v 4.x, but have a few questions on how to make a "clean" start.

We have a few mods, such as photopost and the 3.x blog system which we wish to get rid of, but a few mods such as "miserable user" which we wish to keep.

We're also curious what will happen to our current design and templates when we upgrade, and what is the best way to handle these during the upgrade/move with the least headache possible.

Any suggestions?
