Answer : Notes 4.6 to Domino8.0  Upgradation

In that case I'd really start with a fresh server. The effort of upgrading mail databases only is very small, probably just one command on the server console is enough:

      load convert -u mail\*.nsf * mail8.ntf

To start using the much improved database format of R8, type also a

      load compact -c mail\*.nsf

Just start installing a new server, if it all goes wrong you can always start all over again while the old server is still in place.
