moving a database from one server to another.

NT 4.0, IDS 7.3 Hi all I'm moving a small database (4gb) from one server to another as a favour to a mate. I'm savvy with IDS on Unix but have never used it on Windows. The database doesn't have any blobs. And the source and target operating systems and Informix versions are identical. The target machine has much more disk and memory. Looking through the manual it looks a little different to Unix. May I ask you a few questions? (Pardon my ignorance in advance). Should I use onunload/ onload or dbexport/dbimport? Do I need to run these commands through a command shell or is there a nice menu driven system to use? Do I need to specify tape block sizes or does the block size default? Are there any "undocumented" problems that I should be aware of in this process? Any other comments? Thanks in anticipation :)
