I'm about to upgrade one of our HDR pairs from a relatively old version of 11.50 to the most recent drop to resolve a minor bug. Since an upgrade is something you may be interested in doing some day, I thought it would be a good idea to document my steps here.
Normally an upgrade from xC3 to xC8 would be trivial and low risk since we're only upgrading the minor versions, but with the addition of Compression in xC4 any upgrade from xC3 or lower must be treated as a major upgrade which includes a reinitialization of HDR.
The information provided applies to the Informix Server Version 11.70.xC2
