Upgrading

[isc-rsingh]

• Assuming IPM is namespace-specific, can we provide a system level option that defaults to installing IPM in every namespace which is more aligned with our current setup of a per-namespace IPM version?
• Old ZPM upgrading to new IPM:
  • Modules are still namespace specific.
  • Need upgrade step in IPM.Installer to copy data from old global to new ones.
  • Packages themselves installable by old version of ZPM should still be supported by new version of IPM

Anyway, upgrade options should be delivered with the first version of IPM
Do not want to repeat the first version of IRIS issues again.
