Moving Published db to different server (cannot reinitialize)

When I've talked about nosync initialization, this was
connected with subscribers. When moving the publisher to
another server of a different name I have always scripted
out the publication, edited it to alter the servernames
then run the script on the new publisher and
reinitialized. If the tables are large, you could
compress the BCP files (winzip9.0) with an alternative
snapshot location being used for the subscription, or
DVDs etc. BTW we have a 35GB database, 20GB of which is
snapshotted occasionally and using fileshares the whole
process takes 2 hours or so.

how long does it take to distribute that snapshot
to a wan subscriber?
Ok on the compression part. Basically I've run
into where windows wont compress a bcp file over
2gb. I guess that is why you are saying use
winzip or rar. Do a normal snapshot to an
alternate location. Then compress those bcp
files, send those compressed bcp files over the
wan link to the subscriber. They unzip them and
insert that information. They I would "push the
new subscription" at that point? How do i keep
the distribution agent from trying to push the
original snapshot that was made , and only push
the data that is in the log reader?
I guess I could move the snapshot files so it
will just move on to the data that is in the log
reader?
Thanks for the help on this paul.
