On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Question

Will KernelCare extension work after Plesk server migration?

Answer

Due to a KernelCare limitation, license for KernelCare extension needs to be manually unregistered on the source server in order to be used on the destination.

To do it, perform the following steps after the migration is finished:

  1. Connect to the source server via SSH.

  2. Run the following command:

    # kcarectl --unregister

    Hi Leonid Gukhman,

    I have tried to run this command and I see the success message. But the extension still seems to stay licensed. Can you please also advise on how to deploy this on the new server. I do not see a way of extracting the license information from the existing server. It does not seem to have a license key/id anywhere.

     

    thanks,

    The KernelCare license is bound to the main Plesk license key, so it is installed on the new one, as well.

    After running the --unregister command on the old server, retrieve keys on the new one under Tools & Settings > License Management.

    Hi Leonid Gukhman, I had tried this prior to my comment and the installation does not find any licenses as such.

    I feel that the two servers may have different independent licenses. These are two separate dedicated machines provided by ionos. Separate IP addresses also. How do I proceed in this situation?
