Convert mail merges made in 2000 to 2003

[BaT]

Well we have about 100 mail merge doc files here at work. My boss is looking for a way to easily convert these mail merge documents made in word 2000 into 2003. They are using a header file in 2000 and 2003 seems to store the header info inside the actual word document now. Is there an easy and quick way to convert all these documents to the 2003 format with a wizard or something so no1 has to go and remake all these documents by hand. These documents txt input file is auto generated by a different program that executes the desired sql for that mail merge type doc and outputs to the txt file. An easy to read guide would be appreciated as its been a hell of a long time since i had to do any making of mail merge stuff and i never did complex stuff like whats been created here.
