Hello All,
I have upgraded JIRA to 8.13.11 and after that Bigpicture was asking upgrade our mssql schema from 85 to 185.
I have started upgrading but after some time got Bigpicture loading Crashed.

I have gone through logs and found error:
com.microsoft.sqlserver.jdbc.SQLServerException: 'pk_AO_0456E7_T_CORE_TASK_SURROGATE_ID' is not a constraint.
How to solve this?
