Change server

After purchase a license for serve edition.
My laptop server stolen or damaged.
Am i need to purchase new license?

No, you need to enter the license key again after installing Server edition on a new server. It is actually strange practice to install a server edition on a laptop. It is better to instal in on a desktop/server/tower fixed place or a VPS.

Please note that if your Server license is more than a year old and did not pay for Maintenance for the subsequent years that you should install a version for the relevant year from Github Releases · Manager-io/Manager · GitHub

See emphasis added:

No Monthly Fees

Server license is a one-time purchase and entitle you to perpetual use. The first 12 months of maintenance - product updates and support - are included free.
