Manual Recovery An upgrade with manual recovery (using the -m option with the bcmsysupgrade utility) formats the ﬂash memory after backing up the current software, then copies the upgraded ﬁles to the bridge/router. If the upgrade is not successful, you must restore the software from the NMS.

If you are upgrading your hardware as well as the software, you can easily recover your old hardware if the upgrade is not successful. However, because you erased the ﬂash memory on the new hardware, you will need to restore the original software from the NMS if you want to return the new hardware to its original state.

Table 2 lists the memory requirements for each software package on the platform you are upgrading to. If you are upgrading to an earlier version of software, see the guides that came with that version for the memory requirements.
