We are in a mixed (McData / Brocade environment) in Open Mode. I'd like to change the interop mode to McData mode because in open mode, 70% of the usefull brocade commands (like fcping) are not available.
As changing interopmode will wipe all the configuration, i would like to be able to backup/restore the configuration.
I suppose doing a configupload / change interopmode / configdownload will not work.
Do you know a way to change the interopmode without having to reconfigure all the fabric ?

Teoman, see below. For more details consult the CLI guide.
With other word, if you change the IM, the Zone must be re-config now.
When changing From Brocade Native to McDATA Fabric or McDATA Open Fabric Mode
McDATA Fabric mode only supports a user domain ID range of 1-31 which is added to the
domain offset to get the PID domain range. The domain range for McDATA Open Fabric mode is
97 to 127. The existing preferred configuration must be changed to a value within this range
before the conversion is allowed. If your domain is out of range, the system makes a best
estimate of what the domain should be. For example, if your domain is 0x92, going to McDATA
Fabric mode 2 will end up at domain 2 mask out upper bits. Or, when changing to McDATA
Open Fabric Mode 3, your domain will end up at 0x62 98 decimal. Mask out upper bits, and
add a domain offset of 0x60.
Existing zone configurations, defined and effective, will be erased. The switch assumes the
zone configuration from the fabric it joins or a new configuration must be configured.
When changing from McDATA Fabric or McDATA Open Fabric Mode to Brocade Native Mode:
Existing zone configurations, defined and effective, are erased. The switch assumes the zone
The system reboots and the configuration is lost.
