Hi @Elisha George ,
first of all you should check if all resources could be moved to a new subscription. There is a list available with this information: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/move-support-resources
With the Azure Resource Mover it's possible to move resources between subscriptions: https://learn.microsoft.com/en-us/azure/resource-mover/overview
