How do we update system uri identifier after changing the hostname of orion servers?

Hello All,

We are facing issue in creating snow incident via solarwinds alerts.

Recently we changed the hostnames for orion servers and updated the tables as mentioned in migration article. 

Niw integration alert giving error action failed system.string not support deserialization of array.

Upon checking with solarwinds support found old server name entry website settings "systemuriIdentifier". Solarwinds update uri from DB manager. Still the same result.

Post update now old server name is not showing in error but still giving the same error.

How do we update system uri identifier after changing the hostname of orion servers? 

Thanks,

Alankar
