And since this consumes so much time (let alone shuting down the computer
for installing the extra disk ;-) ) I would first try to to the upgrade.

To be on the safe side, it might be good to prepare
/usr/local/lib/glibc2.1 and copy there all the libc2.1 libraries. After
the upgrade, in case some programs has problems with glibc2.2
(theoretically glibc2.2 is upward-compatible, or whatever the term is. I
figure that in practice this won't always work) you run the program with
LD_LIBRARY_PATH=/usr/local/lib/glibc2.1:$LD_LIBRARY_PATH

Unfortunetly I'll have to try it some day :-(
