Overview:
Feature 1404 "Graceful Upgrade IMG software in SS7 Network" adds to the IMG the ability to easily upgrade the IMG System Software in a Network that consists of an SS7 Primary Node, SS7 Secondary Node, and SS7 Remote Nodes. Previously, upgrading system software would require bringing all the nodes down at once, upgrading software, reconfiguration, and then start processing calls again. Feature 1404 adds the ability to upgrade the software in each individual IMG in a step by step process which will limit the number of calls lost during this process. Feature 1404 supports upgrading the IMG for up to two CI (Controlled Introduction) releases back. For example, anyone running software 10.5.0 or 10.5.1 can take advantage of this feature when upgrading to 10.5.2 software. The procedure below explains the steps required to accomplish the upgrade with a minimal amount of downtime.
