I did the same thing with the channel archiver and it took a while to resolve. The heart of the trouble is that the cgi data server (ArchiveDataServer.cgi for the channel archiver) was unable to run due to a number of issues. The archive viewer couldn't see the data because ArchiveDataServer.cgi couldn't start. The final solution for me was to recompile the archiver from scratch on the 64 bit machine and use the xml index files and data from the 32 bit machine. I had to have a lot of help doing this, so I won't be very helpful on how to do that I'm afraid. However, my goal was to get the archiver running as well as being able to see the data. Perhaps as long as you can get the archive data server working you don't need to do this. I would suggest transferring ArchiveDataServer.cgi from the old machine to the new machine with all of its libraries (the 32 bit ones) as a starting point.
The channel archiver manual may help. It has a section on testing this server. It is woefully out of date and quite terse, but it can at least show you where to place the cgi server and how to test it: http://www.slac.stanford.edu/grp/lcls/controls/global/sw/epics/extensions/ChannelArchiver/manual.pdf.
If you are using the RDB archiver, I'm afraid I can't help.
Hope that at least gives you a starting place!

Hi,
I copied some archived data from a 32-bit machine to a 64-bit machine. I'm not able
to read the data. If I do an ArchiveExport I see only a very small number of entries.
I'm guessing that I need to regenerate the indices, but I've not been successful in doing
so; perhaps I'm not understanding the manual.
Please help. I've wasted an inordinate amount of time.
Thanks,
Pierrick
