downgrading to older version of a perl module

[miek_gln]

two perl modules were recently upgraded to newer versions on a development server. they appear to be causing problems with a perl/cgi applciation that runs on the box (the modules were XML::Parser from v2.31 to v2.34 and XML-DOM from v1.42 to v1.43).

what is the best method to downgrade back to the older versions of the modules?

can i just install the old modules as if i was installing a new module or do I have to remove all the files installed with the new modules before reinstalling the older modules.

thanks for any advice
mike

Ideally the Perl applications should be updated to be compatible with the new modules. But you should be able to normally install the old copies over the new ones. There may be some unecessary files lingering around if the new version had any additional files, but they shouldn't cause a problem.
