I moved my SQL server and SQL database from one resource group to another one.
The SQL database exists in the SQL server with Online status. When I try to go on it. I got the following error: "This resource was not found, it may have been deleted. /subscriptions/{subscription-id}/resourceGroups/{resource-group name}/providers/Microsoft.Sql/servers/{sql server name}/databases/{database-name}".
This is normal. You may have to wait a few hours and everything will be fine again. Meanwhile you will keep getting those "This resource was not found, it may have been deleted. [...]" error messages. Sometimes you may have to wait more than just a few hours, to be sincere you may have to wait a day, but everything will be fine again.
