Hi Saurin,

Best approach and the fully supported one , is with below steps:

1. Create a new subnet with a larger, non-overlapping range.

2. Create a new node pool on the new subnet.

3. Drain the pods from the old node pool that resides in the old subnet.

4. Delete the old subnet and old node pool.

Hi Saurin,

You can find guidance on migrating an AKS cluster Here, a lot of it will depend upon your application and tolerance to downtime.

Anyway, if your plan is to build new AKS cluster and shift the load to it i will highly recommended opening a case to Microsoft support team for specific support per to your requirements.
