written by: Murray White - Solution Architect with Vision SolutionsThe following video demonstrates a migration of existing storage, to new storage server (on the same server), on a Windows Server 2008-R2 server. Key Features of Double-Take Move 6.0 * Migrate full servers (P2P, P2V, V2V, V2P)* Data migration (volume to volume same server or to different server)* 60 day time limit (from activation) to perform the migration* Real-time, byte-level replication* Minimal downtime (zero downtime during synch/replication... minimal downtime during cut-over)
Your source server must meet the requirements below. In addition, each target server must meet certain requirements, however, they depend on the type of target server you will be using. See the specific requirements for each migration type in the Double-Take Move User Guide for target server requirements.
Additionally, verify the machine where you are running the console meets the Double-Take Console requirements (see User Guide), and review the mirroring and replication capabilities to understand the type of data that Double-Take protects.
Windows Server 2003 or 2003 R2 Datacenter, Enterprise (i386, x64), Standard (i386, x64), Web Server, Small Business Server, or Storage Server Edition. Each of the Windows 2003 operating systems require Service Pack 1 or later.
Windows Server 2008 or 2008 R2 Datacenter, Enterprise (i386, x64), Standard (i386, x64), Essential Business Server, Web Server, Foundation Server, Small Business Server, or Storage Server Edition
File system—Double-Take supports the NTFS file system. FAT and FAT32 are no longer supported.
System memory—The minimum system memory on each server should be 1 GB. The recommended amount for each server is 2 GB.
Disk space for program files—This is the amount of disk space needed for the Double-Take program files. For Windows 2003, this is approximately 300 MB. For Windows 2008, this is approximately 375 MB.
The program files can be installed to any volume while the Microsoft Windows Installer files are automatically installed to the operating system boot volume.
Make sure you have additional disk space for Double-Take queuing, logging, and so on.
Server name—Double-Take includes Unicode file system support, but your server name must still be in ASCII format. If you have the need to use a server's fully-qualified domain name, your server cannot start with a numeric character because that will be interpreted as an IP address.
Protocols and networking—Your servers must meet the following protocol and networking requirements.
Microsoft .NET Framework—Microsoft .NET Framework version 3.5 Service Pack 1 is required. This version is not included in the .NET version 4.0 release. Therefore, even if you have .NET version 4.0 installed, you will also need version 3.5.1. You can install this version from the Double-Take CD, via a web connection during the Double-Take installation, or from a copy you have obtained manually from the Microsoft web site.
Windows firewall—If you have Windows firewall enabled on your servers, there are two requirements for the Windows firewall configuration.
See Firewalls section of the User Guide for instructions on handling firewalls in your environment.
