  1. Hello, I have a few servers on a 192.168.150.x subnet. I need to move all my network equipment to a different site and I need to use a different subnet such as 192.168.151.x. I will be using a VPN site to site at the beginning until my point to point is insatalled. so I'm wondering if I change my DC and file server IP to a .151 subnet would I be asking for trouble? are there any records or dns records that will get screw up or anything that you can think of?

    please let me know if this is something you would recommend or if I really have to do it in a different way.

    thanks
    Mm

    hmm; Leave the existing entries for the DC as-is.
    Then create the shadow entries which mirror the real site and use a prefix or suffix in the names;
    • if the true DNS is name foo.dns.domainName; then the shadow might be s_foo.dns.domainName
    • if the primary DB server is DB1.domainName, then use s_DB1.domainName
    migrate from DB1 to s_DB1 & run regression testing here

    when done and all regression testing is final;
    SWAP:
    DB1.domainName -> x_DB1.domainName
    s_DB1.domainName -> DB1.domainName​
    and leave x_DB1.domainName for historical backup

    The entire world is controlled by what is in your DNS;
    today it's the existing system,
    some day soon, it's the migrated version​
    and no one will ever know the difference
