Migration Dependencies
In addition to the bootROM and application dependencies, there are certain
restrictions with regard to upgrading or downgrading from one bootROM
release to another bootROM release. These restrictions are typically caused by
the addition of features that change the way bootROM provisioning is done,
so the older version become incompatible.
There is always a way to move forward with bootROM releases, although it
may be a two or three step procedure sometimes, but there are cases where it
is impossible to move backward. Make special note of these cases before
upgrading.
Note that:
• 1.x cannot be upgraded to any 2.x automatically
• 2.0 and 2.1 can not upgrade past 2.4
• Only 2.6 can upgrade to 3.0
• 3.0 cannot be downgraded
For example, a two step upgrade would be necessary from bootROM 2.1 to
bootROM 2.5. A direct upgrade is not supported, but upgrading to bootROM
2.2 first, then upgrading to 2.5 will work.
Downgrade restrictions are limited to major releases. Going from 2.x to 1.x and
from 3.x to 2.x are both impossible in the field.
