Why would you do that ?
Just put the host in maintenance and the system will evacuate all VMs and another host will be promoted as SPM . 
Once the host is in maintenance - you can proceed with your tasks.

P.S: Don't forget to remove the mainteance mode once you are over.

Hi Strahil,
I did not tell you that this is the first thing I tried but it didn't work because SPM can't be activated in another host,
then I tried to manually move SPM without success.
Any ideas ?
Thanks a lot !
Best Regards
Enrico
