Change local system account to managed service account (MSA) after installation

Hello there

The help file states that it's possible to use a managed service account (MSA) instead of local system account:
Setting M-Files Services to Use a Managed Service Account

But it also states that this should be done before the M-Files installation.

What if I want to change to a managed service account (MSA) after the installation?

Is this possible? Are there any special things to consider?

Thanks & cheers
