Hello,

My old XP Pro PC has ActivePerl 5.8.8 Build 822, with some add-on modules I use.

Two questions concerning my new XP Pro machine:

1) Pros and cons of installing 5.10.0.1005 vs 5.8.9.826 (both via .msi)?
Specifially, if I install 5.10.x will my existing scripts run automatically,
or do I need to change their initial lines? Some of my scripts need to work
with the perl dynamically embedded in VIM.

2) For either choice, what is the best way to list the modules I have on my
old machine and to get the latest versions of them on the new machine?

Thanks.

--Suresh

In two sentences:
Pro: 5.10 has some new features: http://search.cpan.org/~rgarcia/perl-5.10.0/pod/perl5100delt a.pod
Con: 5.10 has less pre-compiled PPM modules.

99% that you don't have to change anything in your scripts, but nobody would guarantee it.
Just check: installing ActivePerl takes only minutes, you can always rollback if something goes wrong.

ppm profile save filename

copy "filename" to new machine, and then

ppm profile restore filename

Thanks; I will stay with 8.9.x for now.

Installed the latest ppm-profile, but got this error message:

> ppmprofile --verbose save

c:\opt\perl\site\bin\ppmprofile.pl save is not supported for PPM4 yet at c:\opt\perl\site\bin\ppmprofile.pl line 81.

My directory structure on the old and new PC is the same. I
suppose things will work if I copy over the site directory; but
will ppm on the new PC new about the installed modules?
