4.4 Upgrade Execution

In DSR, there are multiple methods available for upgrading a site. The most efficient way to upgrade a site is the Automated Site Upgrade (ASU) feature. As the name implies, this feature upgrades an entire site (SOAMs and all C-level servers) with a minimum of user interaction. Once the upgrade is initiated, the upgrade automatically prepares the server(s), performs the upgrade, and then sequences to the next server or group of servers until all servers in the site are upgraded. The server upgrades are sequenced in a manner that preserves data integrity and processing capacity.

Automated Site Upgrade can be used to upgrade the DSR/SDS servers. However, Auto Site Upgrade cannot be used to upgrade IDIH servers at a site.

Additionally, there are separate procedures described in the upgrade procedures to support either a manual or automated approach to upgrade any particular server group. When planning upgrades the Site Upgrade Methodology Selection section of the upgrade procedure should be carefully reviewed. The use of the automated methods (Auto Site or Auto Server Group) for DA-MP server groups should be carefully considered regarding potential negative traffic impacts. The ASU enhancement in DSR resolves this issue. The user is now instructed to rearrange or add cycles to create a suitable upgrade plan.
