In reply to Sahar Nassif. Hi Sahar, You may have affinity rules created to ensure that those 5 VMs are configured to stay on that particular host. I would check that first. Also, there is an algorithm that DRS uses and it isn't always accurate until vSphere 7 came out and provided a better experience. It may be that the DRS algorithm is calculating that those 5 VMs are better off on the original host even though its not.

Our DRS is configured to be fully automated, and there is a configured vm-vm affinity rules set to keep about 5 VMs working together on same host
However every time i try to move the 5 VMs from their host to different host

after they all successfully moved to the target host, they revert back to original host although the target host resources better than the source host

what could be the reason?

Hey, Nice Article but you forgot to mention what vsphere license is required in the requirements section.
