Mark, I have been advocating this migration in our Sysplex and here are excerpts from an emails I wrote with links that may help.
The first IBM implementation of tape sharing back in MVS/ESA 5.2.2 had many faults. The rewrite IBM did a while ago commonly called ATS Star works very well and is included free in base z/OS. A number of other sites have used this base feature to replace GTAF (MIA). <$SNIP> It is documented in SA22-7625 MVS Setting Up A Sysplex Appendix G.0 Appendix G. Specifying Automatic Tape Switching (ATS STAR) http://tinyurl.com/aswzw Or http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2F132/CCONTENT S?SHELF=IEA2BK34&DN=SA22-7625-06&DT=20030423145429 See also GA22-7525 HCD Planning 2.3.3 Using automatic tape switching http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2G841/CCONTENT S?DT=20040421150502&= Or http://tinyurl.com/ceo6x Finally a really excellent set of SHARE presentation by the designer Scott Fagen (IBM) and a couple users. <SNIP> from the SHARE web site here http://ew.share.org/proceedingmod/abstract.cfm?abstract_id=4823 2811 - ATS Star Implementation, Diagnostics, and User Experiences Available with z/OS 1.2 and installation of selected APARs, ATS Star improves the availability and system management characteristics of MVS Automatic Tape switching function. The speakers will discuss: The new design for Sysplex tape sharing Requirements for implementation IEFAUTOS migration Problem diagnosis and recovery User experiences OEM tape sharing migration I hope that helps.

I have a good understanding of both MIM and GRS both have never actually done a migration before. Would anyone have any useful information (presentations, hints & tips) when considering a migration.
