How migrate from version 6.1.7 to 7.5.5

[LuisCarlos]

Hi All,
I´m using Espocrm 6.1.7 version and need to migrate to Version 7.5.5

Is possible to do this, without lost of actual data stored in MySQL?

Thanks.

Hi,

You just need to run from CLI:

bin/command upgrade

Nothing will be lost, everything is backward compatible. Though, we recommend to make full backups just in case. If something goes wrong, one won't need to spend time to find how to revive the instance, but just restore the backup.

Keep in mind that with EspoCRM version 7.3.0 PHP 7.4 support was dropped. So you might need to upgrade your php version and update your webserver config.
