We are currently upgrading from ARIS 7.2 to 9.8.  I'm curious if most organizations use the ARIS 9 symbols and have updated all of their existing models as part of migration from ARIS 7.2 to 9.8 or if most keep using their ARIS 7.2 symbols to prevent having to manually fix all existing models since the new symbols are much larger than the old ones?  Any suggestions / lessons learned of what has worked well or not so well would be appreciated.  Thanks.
