More than likely there will be a database upgrade patch at some point. The one thing to check is the mods you are planning on keeping as they may not be usable with the new release.

For us, there is one mod that is critical. It is the"Added Order Status w/ emails" which we use in conjunction with the X-AOM module. The rest of the mods we have we probably don't need, except for some sort of SEO module (which I think will be standard in 4.2 if I remember correctly). We will not be upgrading until we can confirm that we will still be able to use that mod.

One thing to be aware of is that most mods have modified your database, and it would probably be best to remove those entries in your database before doing any upgrade. What might work best is to use a standard install (no mods) of your current version of x-cart, checking the standard database against what you are presently using and removing the alterations to the tables performed by the mods, making sure that everything is working properly with the standard install on your new database. Then upgrade a copy of that database.
