Renaming database after log shipping.

In order to move from one data center to another, I am planning to use log shipping.
Lets say,

Current Data center - DC1
Current Server- S1
Current Database- DB1

New Data Center -DC2
New Server -S2

Now, on the New Server S2, I already restored DB1 as DB1 for QA testing. QA has to do some testing before we move from DC1 to DC2. In the mean time, I need to start log shipping from S1 to S2, so that we can fail-over to S2. Now since DB1 database is already present on S2, I can not use the same name. I will have to use some other name (say DB1_New).
I can not wait for QA to finish their testing. I have to start log shipping before that. When QA is done, I will delete the DB1.

So for this log shipping, -

Primary - S1- DB1
Secondary - S2 DB1_New

So when we fail-over, we will have the database name as DB1_New. But all the apps use the name DB1. So I will have to rename the database as DB1.

So want to know, will this renaming the database (DB1_New to DB1) cause any issues?

Anyone had similar experience?

Thanks

Generally, you would be okay - some of that depends on how you have things configured, how long you are going to ship the logs before failing over to the other site, if logins/users have changed. You would want to consider what jobs you have running on the server, how this impacts your fail over plans and backups, anything pointing to the DB_new database name would need to be evaluated, etc. After the fail over and rename, you'd probably want to do a full backup of your databases, make sure the users are all intact, etc.

hi,

even if u have the same dbs in both source and detination prior to configuring log shipping, u need not create a new db in secondary instead u can drop the db in secondary......and while configuring log shipping u have the option to create the db @.destination if the db doesnt exist there already........if the failover is done properly all users from primary will be able to connect.....ensure that wherever u specified the db1 name in application change it to db1_new in your scenario........
