  • Applies to:
  • Plesk 10.3 for Windows
  • Helm 3

Symptoms

When trying to run pre-migration Helm3CompatibilityChecker before performing migration from Helm 3 to Plesk 10, the following warning is shown:

Several domains with dedicated IPs in a package and no shared IPs are globally configured. (Package will not be migrated.)

Cause

Plesk uses a single IP for all domains in the subscription so the migrator has to change its domain IP sometimes.

Migrator uses the following algorithm to choose IP for subscription:

  •     If the domain is the only one in a package, its IP will be used;
  •     If there are several domains in a package, a shared IP of some domain will be used;
  •     If all domains in a package use a dedicated IP and the web service has a shared IP, the service's IP will be used;
  •     If the web service has a dedicated IP, a shared IP of one assigned to the web server will be used;
  •     If all IPs on the web server are dedicated, the above error will be reported and the package will be skipped.

Resolution

To work around this issue, it is necessary to add a shared IP to the web server.
