I have upgraded your MM version to 6.0.0.110
Mistake you guys were making is that the entry deletion in VERSIONHISTORY as I could see there were many rows deleted from that tables including first entry of “Initial Install”. There should have been at least 79 entries in this table starting from VERSION_NUMBER 2.1.18.0 to 5.37 or respective entries.
You just need to delete one row which contains VERSION_NUMBER = 6.0
You are good to go now, please check and let me know.
