Just got the word that Our Data Center Hosting Vendor will be changed in the end of the year.
Bunch of the SQL Servers would need to be relocated to another hosting vendor.
Among the dozens of DBs, the Biggest DB is around 400GB.
Most of the Servers are running with SQL Server 2005 sp3, one server with SQL 2000.
I know they will set up all the servers completely new. There will be SAN.
And I will be responsible to migrate all the Data to the new hosts and work with the APP people to get things run in the new environment.
Wondering there is anyone who has gone through this kind of process?
What is the best way to get the data to the new env.?
any lessons/advice/suggestions will be greatly appreciated!
TIA.

Can you afford a down time?

1- Pre create all databases in new location.

2- Take a final full backup and put it on an external disk drive

3- Ship the external disk drive overnight

4- Restore in new location

5- Be happy ever after

PS: Don't forget to script jobs, credentials, etc in the old location and apply those scripts on the new location 😉

offcourse Pablo (Paul) Berzukov covered most of the points.

In addition to that, now you have huge SAN in hand. So you can scatter your data files, log files of user database(s) and TEMPDB files into different disks (Check your server configurations like how many Processors (CPU) and memory and also verify your what level of RAID)
