BULK DNS ENTRY CHANGES

Dear All,

I've a Zone (xx.com) running on windows server 2008R2 STD with DNS Role.

I've lot of DNS entries for all internal URL which are public IP's. Now we are migrating to MPLS and moving all the public URL's into Private.

For Eg. XX.com 103.X.X.X --> XX.com - 172.X.X.X

but there are close to 200 links in a way in want to change. 

So i'm just checking if there is any possibility of completely importing complete DNS into once CSV, make all the 200 URL's with changes IP's, and then re-import to DNS server.

Any answers would be of great help.

Thanks
