I am in the process of migrating some lists from 1.8d to 14.4.

Are there changes to the subscriber info that would prohibit performing a GET 
<listname> on the 1.8d platform and then (after appropriate header corrections) 
performing a PUT <listname> on the 14.4 platform?

While I can script out a lot of stuff based on the query command to migrate the 
user base, it would be nice to also retain the date subscribed, as well as just 
save a lot of work.

If that isn't possible, is the subscriber options field documented anywhere?

Thanks,
Randy
