A VMM Pro license is activated on one Synology NAS, and the whole Virtual Machine Manager cluster borrows it from that host. That works until the day you remove the host the license lives on. The moment it leaves, every remaining host shows the VMM Pro license as Invalid with a 30-day countdown, even though the key itself is paid for and still has months left. This guide shows the fix we used on our own cluster on 18 October 2026: add the same key again on a host that stays, accept the migration, and the license moves across in about a minute. Every screenshot below comes from that run, with the license keys, account and serial number blurred out.<\/p>\n\n\n\n

Ponto SynoPower Club:<\/strong> Our FlashStation FS2017 held the VMM Pro license for the cluster, but it is loud, so it only woke up at night to collect replicas and then went back to sleep. Once our DS1621xs+ and DS1525+ could protect each other, the FS2017 had no job left, and I removed it from the cluster. The console immediately turned orange: Invalid, 30 days remaining. There is no “transfer” button anywhere in Virtual Machine Manager. The fix turns out to be hiding behind the ordinary Add license button, and the dialog that confirms it is the only place Synology spells the move out. I recorded the whole thing so you do not have to guess.<\/p>\n<\/blockquote>\n\n\n\n

What Happens to a VMM Pro license When Its Host Leaves the Cluster<\/h2>\n\n\n\n

VMM Pro is sold as 3-node and 7-node packs, valid for one or three years and not refundable once activated. You activate the pack on one host, and that host carries it for every NAS in the same cluster. The license is tied to that host rather than to the cluster, so when the host is removed it takes the license with it into its own single-node cluster.<\/p>\n\n\n\n

The hosts left behind keep the key in their license list, but its status changes to Activated in another cluster<\/strong> and Time Left reads Invalid<\/strong>. The summary panel switches to Invalid with 30 days remaining<\/strong>, and a link warns that some VMM Pro features will no longer be available after 30 days. Your virtual machines keep running during that grace period; nothing is shut down. The countdown is simply your deadline to put a valid license back.<\/p>\n\n\n\n

Why We Removed the License Host From Our Cluster<\/h2>\n\n\n\n

Our cluster used to have three members: a DS1621xs+ and a DS1525+ running production guests, and an FS2017 acting as a cold standby. The FS2017 held the 3-node VMM Pro license because it was the first host we activated. It powered on at night, accepted scheduled replicas from the other two, and powered off again. The full design is in our production cluster write-up<\/a>.<\/p>\n\n\n\n

Two things changed. The DS1525+ was upgraded to 64 GB of memory, and every protection plan was pointed at the other production host instead of the standby, so the DS1621xs+ and DS1525+ now replicate to each other. That made the FS2017 redundant, and since it is loud enough to hear from the next room, it was removed from the cluster. The only side effect was the license.<\/p>\n\n\n\n
