Abstract
Provided are a computer program product, system, and method for migrating high activity volumes in a mirror copy relationship to lower activity volume groups. A determination is made of usage rates of multiple volume groups, wherein each volume group is comprised of source volumes at a primary site whose data is copied to volumes at a secondary site. A first selected volume group and a second selected volume group are selected based on the determined usage rates of the volume groups. A first volume in the first selected volume group is migrated to a second volume in the second selected volume group. Updates to the first volume, received while migrating the first volume to the second volume, are copied to a mirror first volume mirroring the first volume at the secondary site.
