Upgrading? Beware!


If upgrading from version 3.n to 4.n there are some significant changes in configuration file format and server startup (as well as functional and performance improvements for that price :^)

With the move from from HFRD to WASD the name and location of the document in [DOC.HFRDHYP] changed to [DOC.ENV] (apologies for any broken bookmarks!)

Be sure to read about significant changes (although this is not exhaustive), and the revised Technical Overview and to a lesser extent the Environment Overview.

If at all possible, restoring the new version 4 tree, reviewing the new configuration and mapping files, etc., adjusting startups, and then migrating any local applications into it, might be the cleanest approach.
