@Kuldeep Singh(OT) Thanks for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.
Moving App Service Plan from one region to another is not supported. But you can move an app inside an app service plan to another app service plan across different regions.
can we see m series in my app plan p1vm2 or other as they are not currently showing
Also, from the App service plan pricing page I don't see we have any app service plan with P1vm2.Could you please check and let us know.
Hope this helps, let me know if you have any further questions on this.
