Hello @Saurabh Tyagi
I have just moved my Azure subscription to another tenant on Sunday using the same manual
https://learn.microsoft.com/en-us/azure/role-based-access-control/transfer-subscription
I have Service Bus resource in my Azure subscription, and there were no any interruptions in my services during/after Azure subscription migration
I have WebApp, SQL ServiceBus, VNetworks, AppConfiguration, IoTHub, Storage Account, ACR resources.
