Hi Gubba Ajith Sai,
To check if you're using services affected by the Azure Update Manager migration
Check Azure Automation if you're using Update Management in Azure Automation, it needs to be migrated.
Portal Verification > Go to Azure Portal > Search "Update Management" see if any resources appear.
Check Log Analytics if your update management is linked to a Log Analytics workspace, check if it's in use.
Use Azure Advisor it may show recommendations about migration.
Just in case Microsoft's have an migration guide: https://aka.ms/UpdateManagerMigration
