Want to migrate a Standard D2s v3 to an incompatible VM size

Question

Is it possible, or impractical?

Current VM size is D2s_v3, that cannot be 'resized' to a B4ms. Would it be technically possible to backup the original D2s_v3, then build a new B4ms by using the backed up VHD of the original D2s_v3?

Answer 1

Hello Robert Sudbury,

Yes, It's possible to migrate your D2s_v3 VM to a B4ms using a backup and restore process.

It involves:

1. Stop and deallocate the original D2s_v3 VM.
2. Create a snapshot or managed image of the VM's OS disk.
3. Create a new B4ms VM using this snapshot.

Possible drawbacks I can think of include: changing VM sizes might affect performance; it may involve some downtime during the process.
