Hi Oriana,


            Actually, the newest versions of TiMOS won't down-grade the boot-loader anymore (it was introduced in 6.0R12, 6.1R7 and 7.0R1). Previous versions, though, should allow you to downgrade. In any case, though, the newest bootloaders are always backwards compatible.

Hello all,


I have a question concerning the software upgrade of a 7710 SR (it should be the same that the one of a 7750 SR): I would like to test the upgrade a few times in my lab. 

Yet I have to make a boot ROM upgrade using the "admin save upgrade" command. Can I use the same command to do a downgrade to the initial version of the boot ROM? If not, how can I downgrade the boot ROM to a former version?


Thanks a lot!

Regards, Oriana
