Administrator’s Guide SoundPoint IP / SoundStation IP
C - 10
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.
