We are using Biblioscape 8 and want to upgrade to 10. We use the program solely to put on the web a specialized scholarly bibliography with about 13,000 references (and adding more), so we are most interested in BiblioWeb. We have customized reference type and output files. How easy would it be to upgrade to Version 10 and migrate our 13,000 references and customized files? I think we bought Professional before, in 2011.
