Re: migration from existing server to new server


Log into the expert-on-demand server and execute this command:

copy_mach -s rx3600 -d rx7640 \
-incl ALL \
-errorfree \
-award_points NO \
-immediate_response_requested YES

...but seriously....

Here's an overview at about 20k feet:

1) get new machine running w/ target OS and optional application software
2) duplicate FS config from old to new.
3) shutdown Oracle and all apps on old
4) copy files from old FS to new FS
can use whatever tool you like:
example: on new machine do this:
cd /target/fs
remsh old -n 'cd /target/fs;tar cvf - .|gzip -1' | gzip -d |tar xvf -
5) do step 4 for all filesystems on old machine. Run several in parallel.
5.5) migrate conf of old to new:
/etc/passwd, /etc/group, /etc/*.conf, /etc/oratab, and so on.
5.7) get the crontab files
/var/spool/cron/crontabs
6) start testing
