The migration was complex enough that we engaged a separate third party ISV to guide us through. This was going from a combination of virtual (STK) and physical tape 100% DLm. Allow several months.

Will the new technology share the scratch volser range or will a new one be used? - will the migration be performed volume-by-volume ('cloning') or dataset-by-dataset (copy)? - do applications maintain their own tape metadata repositories outside of the tape management system (CA-View, HSM, others)? - how many drives/how much time will be available for the migration as opposed to production work? - are the source/target volumes going to be SMS managed or will UNIT esoterics be used? - how many datasets and how much data needs to be migrated vs how much can 'naturally' expire or roll off? What's the target date? - who's going to perform the migration tasks? Contractors? Vendors? In-house staff? There are lots of issues to consider. You might want to have a look at some of the Share proceedings on this topic. I've done a few of these in the past both as general education and in conjunction with our tape migration software (see Share Sessions such as 11020 and 14361, among many others).
