migrating dns to Windows

All,

I have a win2008R2 forest/domain running without AD integrated DNS.  The forest uses a linux IPAM server for DNS.  The IPAM is absolete and there is no vendor support therefore it needs to be decommissioned. I am working on testing a migration plan from this BIND based linux box to Windows DNS.  

Since I have no permissions to configure a zone transfer from the linux box I am creating a new primary non-AD integrated DNS zone in a member server(it is much simpler to test without affecting the prod servers). 

 I have installed the DNS role on a member server, created a new primary zone in this new  non-AD integrated DNS server, I have successfully imported the records from the linux DNS box. As I started testing I realized the  SRV records did not import to the new win dns zone.  It looks like they were not part of the file I downloaded from the linux box.  Also,  since the new test primary windows Zone I created is not AD integrated it did not automatically  create the the usual SRV records folders:  _sites, _tcp, _UDP, domainDNSzones, ForestDNSzones.  

Therefore, my questions are:

     - is there a way I can recreate all the SRV records and folders in the non-AD integrated zone?

    -  can you actually run 2 primary zones in parallel while testing is validated: 1  linux and 1 non-AD integrated

         DNS

  -     or is it best to just decomm the linux primary zone and switch to the windows dns zone at the same time?

thnx
