Yeah it is all you need to do. You need to paste and copy over .nsf files and .ini (these are the binary files). and paste the .ini (this is already a text file).
Let me clear things out further. Domino is available for several different platforms. This is the only platform dependent part of Domino. Some platforms have different MSB firs or LSB first and even using different character encoding schemes EBCIDIC vs ASCII. But whatever the native paltform supports this is not reflected in the contents of .nsf files. So you can use any .nsf file built in any domino platform to another platform without a problem. Furthermore that is domino code executed over the platform but then the data in .nsf files are interpreted by domino they are not "executed" in binary format they are only interpreted.
You're welcome. I hope this helps.
Cheers,
