Db Mirroring

i am for the first time creating the database mirroring.I am moving the all the usr databases and everything from test server to a new server called test1.And from that new server i am restoring on the another new server called test2 for database mirroring.But in the test server , the transaction logs are backup for every 15 minutes.So in this case is there a need to move all the logs to test1 and then to test2 for mirroring?? or there is no need to move transaction logs to the new servers at all??


my secnario
------------
server1 server2 server3
-------- ------- --------
test test1 (moving everything from test) test2(mirror for test1 )

all the transaction logs are backup in test for every 15 minutes. so in this case , do i need to move the transcation logs from test to test1 and test2
or there is not need to move at all??


thanks,
