upgrade 3750 stack containing both 3750X and 3750 switches

[jdchandler-hca]

What's the best way to upgrade a 3750 stack that contains both 3750X and older 3750 switches?

This an an output from my show ver

Switch Ports Model              SW Version            SW Image
------ ----- -----              ----------            ----------
     1 52    WS-C3750G-48PS     12.2(55)SE            C3750-IPBASEK9-M
     2 26    WS-C3750-24TS      12.2(55)SE            C3750-IPBASEK9-M
     3 54    WS-C3750X-48P      12.2(55)SE            C3750E-UNIVERSALK9-M
*    4 54    WS-C3750X-48P      12.2(55)SE            C3750E-UNIVERSALK9-M

I'm trying to load the new c3750-ipbasek9-tar.122-55.SE1.tar and c3750e-universalk9-tar.122-55.SE1.tar using the archive download-sw command but fails because not all switches in stack are compatible with new images.

resolved by combining multiple tftp commands in the same line as follows:

stack#  archive download-sw tftp://server/c3750-ipbasek9-tar.122-55.SE1.tar tftp://server/c3750e-universalk9-tar.122-55.SE1.tar
