Downgrading “i” Series Switches
ExtremeWare 7.4.3 Installation and Release Notes 41
13 Save the new configuration to the primary space.
Do not save to the secondary configuration space until you are certain a downgrade to the previous
image is not required.
Downgrading “i” Series Switches
Assuming that the previous configuration is in the secondary configuration space and the previous
image is in the secondary image space:
1 If you saved an ExtremeWare 6.1 (or earlier) configuration during the upgrade process, configure the
switch to use that configuration with the
use configuration secondary command.
If you did not save an earlier configuration, re-configure the switch or download a configuration at
the end of this process.
2 If you did not save the earlier ExtremeWare image in the secondary image space, download the
image using the
download image secondary command.
NOTE
If you downgrade to an ExtremeWare version that does not support software signatures
(ExtremeWare 6.2.2b56 or later supports software signatures), you must follow the upgrade
procedures in the preceding sections to get back to ExtremeWare 7.3. You cannot switch between
primary and secondary images on the switch unless they both support software signatures.
3 Use the image in the secondary image space with the
use image secondary command.
4 Verify that the above procedures were completed successfully with the
show switch command.
5 Downgrade to the appropriate BootROM version. The
show version command displays the
BootROM version as “Unknown” when the BootROM is downgraded.
6 Reboot the switch.
NOTE
When downgrading to a previous version of ExtremeWare, ensure that the switch configuration
matches the previous version of ExtremeWare or below. Pointing the configuration to a new version
of ExtremeWare and using a previous version of ExtremeWare is not supported. You will get a
warning message from the system when attempting to do so.
7 If you did not save an ExtremeWare 6.1 (or earlier) configuration during the upgrade process,
re-configure the switch or download a configuration.
