Hi guys,
I have a mixed stack of 3750E and 3750G units. Max. feature level = ipbase.
With the Network Assistant I get an error when I try to upgrade the IOS.
I selected this file for the 3750: c3750-ipbaselmk9-tar.122-55.SE9.tar
and this file for the 3750E: c3750e-ipbasek9-tar.122-55.SE9.tar
When I try to run the upgrade this error shows up:

When I try it with:
archive download-sw tftp://192.168.1.123/c3750e-ipbasek9-tar.122-55.SE9.tar tftp://192.168.1.123/c3750-ipbaselmk9-tar.122-55.SE9.tar
I get this error:
Error: The image in the archive which would be used to upgrade
Error: system number 1 does not support that system type.

The current stack looks like this:

------ ----- ----- ---------- ----------
* 1 30 WS-C3750E-24TD 12.2(53)SE C3750E-UNIVERSAL-M

4 12 WS-C3750G-12S 12.2(53)SE C3750-IPBASE-M
BTW: Lets say I have 2x 3750E and 2x 3750G in the stack. Is it possible to upgrade only 1 unit without having a downtime for the others?
Many thanks for your support!
