I am going over the initial docs on upgrading my 7.0.3 system up to 8. Is there any issues with upgrading the domains to 8 and leaving other components in place until later dates? When I did the 6 - 7 upgrade, I upgraded my domains first, and left the webaccess, gwia and post offices running 6. Then I migrated them over as I had time,etc. Can I perform the 8 upgrade in the same path?
