I know this has been asked before, but I have an installation that I want to merge into another.  It is only one portal and I'm actually recreating the portal from scratch, but I don't want to have to make my users re-register, so I need to move them. 

Is there someone that has done this that has a script already done that could do this or anyone used any of the programs out there to do it and if so, are they any good. 

I am a programmer and could go in a figure it all out and write the scripts, but if someone has done it or if the existing apps out there are any good it would just save me a whole lot of time.

Thanks

Sorry I'm reviving this old post, but does anyone know of a cheaper one (don't really have that kind of money with my church and don't need all that functionality) or what would need to be moved to the new DB?
