Upgrade completed.

Heavy slaves migration put to separate task (#492)

comment:5 by Mateusz Łoskot, 13 years ago

Note, during the #492 migration I reorganised management scripts and configuration, so it's more flexible to maintain distributed instances. So, the instructions above are not re-applicable as presented, in case one needs to do it in future, because paths have changed.

The OSGeo Wiki will be updated.
