Briefly, yes, but with care. There are two approaches,
depending on your goal.
If you simply want to open (convert) your RoboInfo project
within RoboHelp HTML, you simply File > Open > find the
RoboInfo projectname.xpj (or .mpj for older versions) and it will
become a RoboHelp HTML project from that point forward. So, you are
not truly importing, but opening the project in a different app.
On the other hand, if you already have a RoboHelp HTML
project and want to import selected topics from an existing
RoboInfo project, the procedure would work this way:
From RoboHelp HTML, you can import topics from a RoboInfo
project just like any other HTML file (File > Import > HTML).
The important thing is to import the RoboInfo topic from the
project's source files and not any files from the "!SSL!\RoboInfo"
folder (or worse, from some files that may be on the web server, a
common misunderstanding). Generated output files have dependencies
that will not work properly, so avoid that at all cost.
Basically the authoring "client" application (RoboHelp HTML)
is the same as its counterpart in RoboInfo Author. The big
difference is the destination where the project is published. With
RoboInfo, the author is usually publishing to a RoboEngine database
application on the web server. This provides such things as
feedback reports, the ability to search MS Office and PDF
documents,etc.
Once you have your RoboHelp HTML project ready you can either
publish as plain WebHelp, or if you have RoboEngine installed on a
web server, you can choose to set WebHelp Pro as your default
layout and publish just as you might with RoboInfo.
Hope this helps.
