Redmine

Hi Guys,

We have Redmine installed on one of the windows 2003 server which i would like to move onto windows 2008R2. Can someone please advise what is the best approach to take?

Current Environment:

Server: Windows Server 2003
SQL: MySQL 5.0.45
Ruby: 1.87
Rails: 2.3.5
DevKit: 3.4.5
Redmine: 1.0.1

Unfortunately we have very little documentation on how it was installed etc. I know that there are 4 Database instance within my SQL and 4 websites.

what would help:

1) Is Redmine compatible on windows server 2008R2 and supported?
2) Is there a document somewhere which has instructions on how to install Redmine on windows server?
3) Can we migrate the data from 2003 os to 2008 R2?

I know how to migrate SQL data from Mysql on 2003 os to 2008r2 os, just wondering if we can migrate the websites in redmine from one server to another.

Thanks in advance to everyone who will provide their valuable feedback on this request.
