Moving CVS to SVN - multiple repositories with different permissions

Planning to move from CVS to SVN, but I am not sure how to handle the
transfer....
1) We have used CVSNT since 2001, but we have not used any specific
CVSNT additions that I know of. THe CVSNT version is 2.5.03.2382

2) The server handles 6 different repositories organized as
subdirectories below E:\CVSREPOS

3) The permissions are different for these repositories and are
handled through Windows file system access permissions via AD groups

4) Some projects (especially in the PC repository) are defined in the
CVSROOT/modules file as a combination of files/folders from different
physical trees.

5) The repositories total 32787 files with a combined size of 7.9 GB.

Now I wonder how I should go about migrating to SVN? What I have read
indicates that the cvs2svn script does not use the information within
the CVSROOT admin directory of each repository, so I guess I have to
re-create something similar in SVN after the files have been
converted?

Does SVN have a concept like the modules file such that one can create
virtual modules for checkout where some files/folders are shared
between projects (common code)?

Can I use Windows Server 2016 as the server for the SVN repository(s)?
