I would like to enquire on the upgrade procedure for changing the WAAA CM running in HA from WAE 612 to WAVE 594. This is my understanding of the procedure:
Downgrade the new WAVE 594 WAAS manager at DR to version 4.4.7 to allow us to form a High Availability cluster with the existing WAE 612 Manager. Decommission the DR WAE 612 with the new WAVE 594 taking it place in the HA.
Promote the WAVE 594 in the DR to be the primary WAAS manager.
Disable CMS on the WAE 612 device at the Primary Site
Upgrade WAVE 594 in DR from version 4.4.7 to 5.5.
Decommission the secondary WAE 612 manager in Primary and implement the new WAVE 594 joining it in a cluster with DR primary WAVE 594.
