Moving Resources Across Resource Groups /Subscriptions

 In this article ,we will talk about moving resources from one resource group to another or from one subscription to another .During this movement both the source and the target resource groups are frozen ,meaning we wont be able to add ,delete or modify any of the resources within the resource group .But there wont be any down time to the functioning of the underlying resources .For example If I am trying to move all resources from sourcerg resource group to destrg resource group ,I wont be able to add more resources /modify /delete any resources within sourcerg and destrg .But if there is a Sql server resource, it can still read and write data from the application and there is no downtime for this resource 

Certain resources cannot be moved and Microsoft has a list of those resources and whether they can be moved across to a different resource group/subscription

Also when moving resources to another subscription ,we need to make sure that both the source and the destination subscription are under the same tenant and also that both the source and the destination subscriptions are active as well

The destination subscription may not have been registered for the resource provider required for the resources that are getting moved .This would also result in error .Hence make sure you register all those resources in the destination subscription

The account moving the resources should have atleast the below resource providers registered .Move permission on the source resource group and write permission on the destination resource group/subscription

Before moving the resources make sure to check the destination subscription Quotas .If it exceeds the limit we might have to extend it 

One important thing to note is if you are moving the resources from one subscription to another the resource and all its dependent resources should be in the same resource group .for example if you are moving a vm in rg1 to another subscription ,first you need to move the dependent resources like subnets ,virtual networks everything to rg1 

follows a three step process 

step 1 :  move all dependent resources to the same resource group

step 2 : move the resources to the new subscription 

step 3 : redistribute the dependent resources to separate resource groups if needed
