Well, you can continue installing (through CPAN) the missing modules you had in 5.8.8 with the corresponding 5.10.0 modules.

It is unlikely that all 5.8.8 modules will run under 5.10.0 as there is no guaranteed binary compatibility between major upgrades of perl.

Saving all of your 5.8.8 modules, then re-installing perl 5.8.8 and finally copying over your existing modules might just work, but I would not trust such a hacky solution in a production environment.

The UNINST=1 option does not do what you think it does. It allows cpan to uninstall older versions from the module your are installing if they are under a different path. As that is a possibly dangerous operation, it is not the default and you have to explictly allow it by setting UNINST to 1.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
