upgrading bitrix using files & database migration

centos9 install

postinstall:

• random root password
• hostname & pubkeys comment
• set-timezone
• yum upgrade
• users+sshd role

bitrix install

./bitrix-env-9.sh

migration plan

assuming you installed centos9 and bitrix on the new server already

1. stop production [bitrix admin]
2. proceed with a backup [bitrix admin]
3. restore backup on new server [bitrix admin] - incl files & database (latter takes a while)
4. sync user uploads folder [sysadmin]
5. nginx ssl setup [sysadmin]
6. update DNS and/or load-balancers PAT rules [netadmin]
7. test services on the new server incl push notifications and email [bitrix admin]
8. enable production on the new server (and stop the old server) [sysadmin]

migration setup

user uploads folder sync

on the new server

rsync -a old-server:/home/bitrix/www/upload/ /home/bitrix/www/upload/
