recovery 400 SQL database in a short time

Hi
        we have 1 SQL server 2008 R2 in city A, there is 400 database in this SQL server, but each database is very small, about 5~10 MB, all 400 database full backup is 2.61GB. now in city B, we have new SQL server 2008R2, i would like to move this 400 database to our new SQL server in one night, as my understand, i can backup all database then copy this 2.61G file to city B, but i do not want to recovery this 400 database one by one maually, so how can i writh the T-SQL script to do this?
        or is ther any other plan to recovery this 400 database to new SQL server?

Yes, you can detach and reattach all the files, but that's going to involve downtime on your main server since the databases will be offline while you copy them. Are you looking to script the backups too? If so, you can just build the statements you want using something like this:

Recovery is similar - Narender's link is actually ideal for doing what you're looking for, so I suggest you take another look there. It will require some configuring but it's about as close as you're going to get.

this script would do your job, place all your backup files in a single directory and then run this script with enough access permissions.

You can virtualize your server and move all virtual machine, this would be fastest way.

yes, but server A in BJ and server B in other city, the network is very slow between this 2 server, i can only export server A to ovf file and delivery the disk to BJ, then import to server B, and when i delivery disk, there have new data in server A database, i need do the sync after server B power on, that is why i want to recovery 400 database. other way, can i detach the db and copy .mdf and .ldf file to server B,then attach them? because the DB file is very small but the database number is 400....., the attach is faster than recovery
