There is no "easy" way to merge them that I know of. You really should not be running 1.9rc1 in a production environment. I mean it... really really!That being said you can do what you want to do but the longer the new one runs the harder it will be. First upgrade the older one to the same version. Then export the DB from both installations. You should be able to take the data from the new one and add it to the sql backup for the old one. (save these since if you screw up it will probably be easier to start over) And manually merge the new with the old. You may have to redo some id#s of staff, ticketID's, etc. There may be a tool to do this sort of thing for you but I haven't looked on Google. If you dont care about the new one that much you can always just upgrade the old one (make backups first!)
