Pranav, I am currently migrating our district from Millennium Via to Koha, and would be happy to share what I've done as well. I rolled my own transformation script in Perl that manipulates the MARC output file and merges in some data from CSV lists that weren't shipped as part of via's MARC export. Since we do have Data Exchange, my process works with the MARC output that III generates. I feel sorry for the work Ian had to go through - ouch! Let me know if you would like copies of my scripts.

Pranav,
You may find some of my presentation from Code4Lib 2010 to be useful. I did the first Millennium to Koha migration (or at least I was the first to claim credit for it!) when I was at New York University Health Sciences Libraries.

Generally speaking, you'll want your bibliographic and authority data out in MARC, and your patron and circulation information in CSV (exported from Create Lists in Millennium). The methods outlined in the presentation are a bit roundabout, as we were in a particularly difficult situation at the time and could not use more standard export methods (like Data Exchange), but they work, and serve to outline the process.
Hope this helps!

Hi,
I am a part of the group who are currently evaluating migration from Millennium to Koha and was wondering if there is a case study which has been done which outlines how has the experience been, common pitfalls or some other useful information which can help us in getting to speed in doing a test evaluation?
If there are any useful links or information you can point out from migrating from Millennium to Koha that would be helpful too with respect to in which format the data should be exported from Millennium, what format is accepted by Koha, how the transformation mapping done.
Thanks and Looking forward to hear from you all.
Regards, Pranav
