Could you send me an error you got with python 2.4 that force you to
install 2.6?
OMERO 4.4.10 should still be supported by 2.4.

I think you can't just replace path. Doesn't yum sort that out?

yum install python26 python26-devel

If you run python console which version do you see?

Python 2.6.6 (r266:84292, Sep 11 2012, 08:34:23)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2

tricky.

Did you google? For example:

All our omero resources run on CentOS. If you have any specific questions
please just let us know.

That is possible. In order to install new instance of OMERO 5 please
follow
https://www.openmicroscopy.org/site/support/omero5/sysadmins/unix/server-in
stall-linux.html

Migration from 4 to 5 should go smoothly, please follow
