Data compare for Global Mirror

Today we run XRC and use the ANTUXDVC tool to compare data between regions. This has historically been useful to discover XRC software + microcode issues that have resulted in data integrity/data loss issues in our recovery region. XRC is EOL and we face a migration to GM but GM has no equivalent function. We have a HA environment that gets built every day post-batch and during recovery IMS and other applications engage in pointer-checking and other procedures - if/when they find an issue we need to be able to prove or disprove that the data made it from Production successfully which sometimes means a full volume compare. If the same sort of compare utility were also available for Synch PPRC we would use it - it has been a lesser priority for Synch PPRC because we don't engage in recovery on the secondary anywhere near as often and we see far less network & other errors given a much less complex SAN.
