1.5.3 - courier to dovecot

Quote from fulltilt

do you think it's possible to switch from courier to dovecot w/o complications during a server move (migration process) or is it better to keep courier for the time being?

• On source server, you disable (not uninstall) all plugins
• You stop the imscp_mountall service
• You synchronize the data as follows:
  
  
  • From source server: (you need first setup SSH key)
    
    
    Code

    1. rsync -ahzP --delete -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" /etc/imscp root@<target_server_ip>:/etc/
    2. rsync -ahzP --delete /etc/mysql -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/etc/
    3. rsync -ahzP --delete /etc/letsencrypt -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/etc/
    4. rsync -ahzP --delete /var/mail/virtual -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/var/mail/
    5. rsync -ahzP --delete /var/www/virtual -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/var/www/
    6. rsync -ahzP --delete /var/www/imscp -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/var/www/
    7. rsync -ahzP --delete /var/lib/mysql -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/var/lib/
    8. rsync -ahzP --delete /var/cache/awstats -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" root@<target_server_ip>:/var/cache/
• You run i-MSCP installer as follow: perl imscp-autoinstall --fix-permissions -dr po

This should works.

• I assume here that SQL server vendor and version will be identical on both source and target server.
• Once done, you'll have to reinstall missing dependencies for the plugins (distribution package) and force plugin update by setting their plugin_status field to toupdate.
