Hello second problem for me. In first last month with SDP update 15250 KO and now with the new update 15260 but with an other problem.

I configured my UpdMgr.bat with value "-DSkipForcedBackUp_15260=true"

And i launch the script run as admin, after select my update and install.

During the check update i have this message : 

REQ:2010: Migration halted due to omproper ESM sequence range for noted data.

FYI : Its not my first update, normally its ok :D

I the logs directory : 

ManageEngine\ServiceDesk\logs\updatemanager\

In the UpgradeStatus : "upgradeType":"au.manual","newVersion":15260,"status":"PATCH_INTEGRITY_COMPLETED"}

And in the updatemgrlog i have this last line : 
[com.adventnet.persistence.DefaultPatchValidator]  [SEVERE] : REQ:2010: Migration halted due to improper ESM sequence range for notes data. Please contact administrator to resume migration.

Actually i have restore my infrastructure with backup BDD and snapshot SDP server.

Idea ? 

Regards,
