    2008 32-bit to Windows 2008 R2 64-bit - HELP.

    I just installed a fresh 2008 R2 on 64 bit machine but how can I transfer all of the server roles from 2008 32bit to 2008 R2 64bit?

    Looking forward to your inputs!

    Thanks.

    AD (I did a quick test from a client to this domain but isn't necessarily to transfer this role.)

    DHCP (Currently using it with reserved ips)

    DNS (Currently at use)

    How can I transfer DNS and DHCP's datas into 2k8 R2 without overlaps to the nodes?

    DNS is easy when you setup the new AD server and make it a DNS server it will automatically make a copy of the data.

    DHCP again is fairly easy - Back Up and Restore the DHCP Database

    Thanks for all of the inputs.

    Now shall I wait until no one use the nodes tonight? Can I transfer those data to 2k8 R2 64bit during the work hour?

    DNS you can do during the day with the promotion of a domain controller. DHCP I would do out of hours.

    You also want to set the bad address check to a few incase there is a few leases outstanding. This means the server checks nothing has them before it dishes them out.

    What he said ^^

    Make sure you restore your DHCP right after you take the backup. Don't take the back then leave it a few hours. It could cause IP conflicts if some leases expire.

    Ok; I'll set 'em up and I'll back up the DHCP and transfer it to the 64bit machine after work hour.

    My plan is to back up the DHCP and wait until tonight to turn off the 32bit machine and transfer to 64 one. Is that a good plan?

    dont turn off the old one stop dhcp. If its a domain controller you will need to demote the machine.

    Ok; but first I want to clarify this steps I planned to do below;

    1) 64bit: AD/DNS setup and setup DHCP/restore the back up from 32bit after work.

    2) Remove the AD from 32bit after the restore DHCP.

    Right?

    Right!

    Make sure you leave the new DC on for a good amount of time, just to make sure everything replicates over. Don't rush things just give them some time.

    Thanks

    Do you have any 2008 R2 domain controllers in the network?

    If not then you will need to run ADprep from the 2008 r2 cd on the 2008 dc. otherwise you will have all sorts of problems.
