Moving on-premises SBS 2003 to Cloud
Posted on 2012-08-15
We have an aging ‘SBS 2003 Standard – SP2’ machine and I have been asked to move it to cloud. I was told that I can do a P2V of SBS and move it to a data-centre like ThinkGrid or SecureVirtual. I just want to make sure I fully understand all the bits before proceeding.
• This SBS 2003 is running our Exchange, AD, NAT/Firewall, DHCP, DNS, SharePoint, Remote Access (VPN), SQL, Printing & File server and internet.
• There are total 60 mailboxes in Exchange and 40 users (only 25 users need access to file shares). Exchange DB at the moment is at 51GB and file shares are over 150 GB.
• It’s a dual-NIC configuration ( Internet Router --> NIC1-external-IP [=] NIC2-Internal-IP --> Switch ) and there is no hardware firewall in place.
• We have a 10Mbps leased line from BT and I am not sure if this bandwidth will cope with all the file shares and Exchange being moved out.
• We also have a Windows 2003 Standard server (virtual) on LAN for redundancy and have assigned it DC, Sec DNS roles and global catalogue.
My assumption is that:
• Switch SBS to single-NIC config
• Put in a hardware firewall between router and switch (e.g, Sonicwall TZ210 or Cisco ASA5505).
• Create a P2V on a portable HD and send it to data-centre
• Once the server is set up in cloud a site-to-site VPN tunnel will be created between the office firewall and SBS so they talk to each other like they are on the same network.
• Onsite users will be able to access SBS file shares and Exchange as usual
• All remote users will be able to access SBS using the VPN method as before. A VPN pass-through will be configured on the data-centre firewall (i.e., M0n0wall) behind which SBS sits.
• Onsite DC will keep replicating all changes from SBS AD (cloud) in real time
• Onsite users will authenticate to Onsite DC and not to SBS in cloud
• Onsite DC will take up Print services role
• Don’t know what will happen with DNS and DHCP in details
I will greatly appreciate if you could please guide me to the right way of doing this. Any documentation will really help.
