  • Unknown Version -> Upgrade to 7.3.3

    Good evening, ladies and gentlemen,

    I'm very desperate. I'm self-employed and my system administrator, who used to help me with my online installations, has quit.
    In the meantime, my hosting company has changed the PHP version. It's only >8.0.

    Now my beloved ESPO-CRM doesn't start anymore.
    I can't make out which one it is. An Error 500 is displayed. Then the note 2019. Since then there has probably been no more update.

    How do I fix that?

    It worked until the beginning of the year, but not anymore.

    Is there a way that I can first find out which version was installed? Probably something around 5.X.
    I did a backup - means I have downloaded this version to my hard drive.

    I've already tried to play a new version of ESPO CRM in a different directory and link it to the old database, but that didn't work.

    Does somebody has any idea?​

    Best, Andreas

    Hi Andreas,
    you can see your espocrm version in "path/data/config.php". => path is dependant .. so generaly is /var/www/html

    have you many customisation ? coding ? .. if no "coding".. then a basic upgrade will do the jobs. If coding, then maybe adapt code !
    you have 3 important folder :
    to make backup and of course database
    have you many file uploaded ?
    all this info can help other to respond

    Maybe, who are your hosting and from wich country (for time )

      Hi there,

      thanks for your quick answer. My Version is 5.5.6. Is it doable to upgrade this one into 7.3.4 by replacing the 3 folders?
      What do you mean with update database? Current MySQL Version is 5.7.40-43.
      Hoster is Hosteurope.

      Okay. Did some homework.

      I saw the upgrade files here:
      And I saw that there is a row starting from my version to the recent one.

      Do I need to go through all of them?
      Means from 556-5614 to 5614-5711 to 5711-585....727-734?

      And where do I find a documentation for upgrading via ftp

      2 think :
      You need update in admin section of espocrm by uploading the file, each by each by following the version.

      As in doc :
      In v5.6 and after you need upgrade by cli ..

      Of course, if you have error 500, this complicate the situation. You need a working espocrm, you can try :

    If you want to start a brand new installation, possibly the easiest choice in my opinion, this post can help you:

    I upgraded from 5.82 and followed the procedures to the current build. For two years prior to this upgrade, everything was running smoothly. I did appropriate backups, so I thought and even looked to the server rewinds etc. Now, every 2-4 hours the CRM crashes again and gives just the blue line across the top of the page. I

    Good Luck !

      No, I don't want to do a brand new, because then I would lost all my entries in the old version. I need to find a way to upgrade from 5.5.6 to 7.3.4 version of EspoCRM.

      With this method you would not lose anything.
