I followed the procedure for upgrading 10.2.1 to 10.2.2. 
Uninstall of previous version , installing the new one and also i followed this for the content store.

I have done test upgrades before and there was no issue when i started the services.
Content store connection test is successful.
He complains that he cannot find the necessary sql files for upgrading from 7.002 -> 7.0027 and throws CM-CFG-5024 which i have never seen before...
I have dbUpgrade7_0002-to-7_0003_mssqlserver.sql files and all other files until 7.0027 BUT i dont have directly from 7.002->7.0027...
Note that i installed 10.2.2 and then i installed immediately latest FP WITHOUT starting the configurator before FP
			
			
			
				Additional info: I tried to start from blank database and the service created the db (version 7.0027) and started ok..
			
			
			
				As i found out there is a PI for this in support portal.
Hope it is fixed in next  version.

Until then the only way to upgrade is by creating a new blank content store and importing the deployment archive.
			
			
			
				Thanks for the followup. Always good for when people search for the same problem.
