Bulk update

    Hi,


    I have 1.2.1 running on about 100 servers. About half of them were running ispcp before and when I migrated to imscp I had to do it manually for each and everyone of them. Now I would really like to update to 1.2.15 and I would like to do it in a bulk without any service disruption, like skip all the rebuilding of php-fpm pools, rebuilding of mailboxes etc. What I would like to do is just rsync the new version to /var/www/imscp run an SQL update, do a config upgrade where needed and restart the panel. I know the plugin part has been rewritten so I would have to disable plugins and enable them a again. But is there anything else. Could you the developers who know every corner of the system tell me what I need to keep in mind when doing an update like this. I have played a bit with the preseed option, disabled the unwanted rebuilding to try to achieve this, but somewhere also I read that the preseed option was not intended for an update. Any tips and pointers would be really appreciated.

    It will be not possible to update imscp without regenerating config files. If you had modifications, just create a listener-file. For updates without ui use the preseed-feature:

    So here what you need to do:

    3-5 can be done automatically with a small bash-script :-)

    As stated by @Ninos, you cannot upgrade without regenerating configuration files. New versions can provide changes in configuration files and this explain why the installer need to regenerate them. With i-MSCP, the standard way to add custom changes is to use listener files. They allows to re-apply your custom changes automatically on update.


    About the preseed feature, you can use it even on update.

    Thanks both of you, I will give it a try. Still I might disable shutting down services while rebuilding some config files, at least until the end of the update progress.
