Just a quick update. I've completed the upgrade: all went well.

No problems in the Perl space. I successful ran a few scripts. My GUIs (Tk) worked as expected. As a test for cpan, I installed Acme: all good. No problems with Perlbrew. The OS has its own, two versions of Perl.

[download]

Not related to Perl, but just for general information: it's ~5Gb download; the subsequent installation took maybe an hour (I wasn't watching it that closely); all of my standard applications (including Firefox, Thunderbird, VLC, OpenOffice, Foxit) worked as previously (i.e. no reinstallation or reconfiguration required); the overall look-and-feel is virtually identical.
