Plesk Migrator shows warning: There is not enough free exclusive IPv4/IPv6 addresses on target Plesk

Symptoms

Plesk Migrator shows one of the the following warnings on pre-migration check:

PLESK_INFO: There is not enough free exclusive IPv4 addresses on target Plesk to map all source exclusive IP addresses. This subscription will be migrated to default shared IP address
Add more free exclusive IP addresses to target panel or change IP addresses of migrated subscriptions after migration

PLESK_INFO: There is not enough free exclusive IPv6 addresses on target Plesk to map all source exclusive IP addresses. This subscription will be migrated to default shared IP address
Add more free exclusive IP addresses to target panel or change IP addresses of migrated subscriptions after migration

Cause

The number of exclusive (dedicated) IP addresses on the destination server is less than on the source server.

Resolution

This warning can be safely ignored and migration can be continued: subscriptions that use exclusive (dedicated) IP addresses on the source server will be migrated to a default shared IP address on the target server.

After migration, you may add new dedicated IP addresses on the destination server and assign migrated subscriptions to them.
