I'm running through the process of applying CU7 to our AX 2012 R2 test environment. All seemed to be going well until part way through the Software Update checklist. After restarting AOS I completed the compile without issue and then there is a line item that appears to be missing a label (@SYP4321845). Running that item has taken in excess of 48 hours so far, but it is actually doing something. Currently it says: @SYP4312413\Classes\LedgerJournalCheckPost\postTrans. The last section changes from time to time.
Obviously this is not something we could do in production as it takes way too long. None of the upgrade documentation mentions any of this so I'm not sure what is going on. Any guidance would be appreciated, just be patient I'm very new to AX.
