A.6.3 Manual DA-MP (N+0) Upgrade Procedure

The following procedure is used to manually upgrade a multi-active DA-MP Server Group. This procedure is an alternative to the normal DA-MP upgrade procedures. This procedure must be executed for all configured DA-MPs of a site, regardless of how the DA-MPs are grouped for upgrade. If 16 DA-MPs are upgraded four at a time, then this procedure must be executed four distinct times.
  1. From the data captured in Table 3-1, identify the DSR (multi-active cluster) server group to be upgraded.
  2. Upgrade up to (½) one half (no more than 50%) of the DA-MP servers in parallel using the Upgrade Multiple Servers procedure.

    Note:

    When using the manual server upgrade method, it is recommended that the DA-MP leader be upgraded in the last group of servers to minimize DA-MP leader role changes.
  3. Execute Upgrade Multiple Servers – Upgrade Administration Appendix.Upgrade Multiple Servers – Upgrade Administration
  4. After successfully completing the procedure in Upgrade Multiple Servers – Upgrade Administration, return to this point and continue with the next step.
  5. Repeat step 2 of this procedure for the remaining DA-MP servers.
