Supported upgrade paths
Direct upgrade paths
5230, 5240, or 5330 appliances with versions 2.7.3, 3.0, 3.1, 3.1.1, and 3.1.2
5340 appliances with versions 3.1, 3.1.1, and 3.1.2
Two-step upgrade path
Appliances with software versions 2.7.2 and earlier must be upgraded twice to get to version 3.2. It is recommended that these systems first be upgraded to version 2.7.3, and then upgraded to version 3.2.
Note:
Although multi-path upgrades from versions 2.5.x or 2.6.x to version 3.2 are supported, these upgrades may fail if the preflight check detects insufficient space on the /boot partition. For example, if the appliance was upgraded from version 2.5.3 to 2.6.1 and then to version 2.7.3 or 3.0, an upgrade to version 3.2 will fail if insufficient /boot space is detected. This problem occurs because the /boot partition is completely allocated on appliances that once used the older versions and it cannot be resized. If you experience this problem, you must reimage the appliance with the version that existed before the failed upgrade attempt, and then upgrade to version 3.2. Using the example just described (version 2.6.1 to 3.1 to 3.2), the appliance must be reimaged with version 3.1 before upgrading it to version 3.2.
