Hello Team - I plan to upgrade to LF 12 over the next few months and I am looking for potential issues.  We plan to Upgrade to 12 LFDS first, then follow with installing the Admin hub.  We  paln to do so across all 3 of our environments in short order. Once this is complete we will install the additional components in a phased approach at a later date.  We have many extensive test plans for the 16 areas across our organization and I am thinking there is not a need to perform this level of validation for the LFDS upgrade.  My assumption is to look across the user store for undefined groups or users, as well as validation of a few forms and workflows.   Does this seem like it would cover the needs for this phase of the upgrade?  i am assuming if there is a problem with LFDS, its not going to be subtle and it will be obvious there is an issue.   Any and all feedback, gotchas is much appreciated.
