Hi Magnus, I have not yet had the opportunity to migrate an Aleph library to Koha. However, as luck would have it, I did a short stint as a cataloger in a library that used Aleph. One of the hurdles that I think you may encounter is how you catalog in Aleph. I had to create a bibliographic record, then a 'holding record' and finally the item record. It was a three tiered setup as opposed to the two tiered setup (bibs and items) that exists in Koha. Hope that helps!

I'm writing on behalf of a library that currently uses Aleph, and is a bit curious about Koha. They want to know if there are any libraries that have made the switch, and what the experience was like. I guess this falls into two categories: - How smooth was the migration? - How big was the leap, in terms of functionality, features etc They would also be interested in which modules of Aleph were used before the change. If you answer me on or off the list I will forward the answers to the library in question, or put you in touch with them for further communication.
