Mantis#2291. Thank you kindly, StrawberryFride for a patch that solves:

User server won't start up for a MSSQL grid migrating from a significantly 
older version to current version due to duplication in three of the 
migrations code files. Patch included takes out the duplicated code from 
the three files so a smooth update should happen on start up.
