1.9.1.6 Database in Upgrade Mode
During a software upgrade, a schema migration is performed, where the configuration data read from the origi-
nal database in flash memory is written to a new database. The data in the new database is converted (schema
migrated) to a new format that is compatible with the load being upgraded to. During this process, the original
database is left intact in flash memory, and the new database is held in RAM memory on the control module.
When in this condition, the database is considered to be in "upgrade mode", and an alarm is raised against the
control module being upgraded.
To get out of upgrade mode, the user must commit to the new load using the SET CARD command on the CM,
which erases the original database in flash memory and then copies the new database from RAM to flash mem-
ory. Alternatively, during duplex upgrades only, upgrade mode can be cleared by doing an abort of the upgrade
process, which erases the new database in RAM memory and causes the system to revert back to the original
database still in flash memory.
