Using OS: Windows Server 2008 R2 Enterprise Edition 64-bit English Version



I setup using ECS Console.
When I try to downgrade "resize datadisk" by using option resize disk.
It doesn't permit.
See screenshot attached.

Unfortunately, ECS does not support system disk shrink.

You have 2 way to do it.
1) Re-build a new ECS with smaller disk and re-install everything again
2) Alibaba Cloud migration tool

Thank you for your help.


Point no. 1 is not possible for us due to several reasons.
I will read about Alibaba Cloud migration tool.
It may be helpful.
