Auto Archive Management - Shift vs. Delete

Currently, there are two methods to 'shift' archives: 1. "Archive_AutoArchiveFileRoot" set to blank 2. "Archive_OverwriteDataOnAutoShiftFailure" enabled Neither method shifts to dynamic archives. We have three sites that merged PI servers, thus half our archives are merged and dynamic. this negates any automated form of archive management. I suspect the two shift methods came about thru an evolution, but there should be a way to 'rotate' thru all archive types so that we don't need to manually manage archives, mess with additional drives, etc. What about a new tuning parameter?: 'Archive_DeleteOldestOnAutoShift' We are only required to keep 'x' number of years of data, we have that requirement, but the drive is full. We can't easily add space, and we can't delete many archives at a time and maintain our minimum history, and we're too busy to delete archives every couple of days. Help! Thank you!
