Hi, Actually, since I am half way in v3, had to use php bin/console doctrine:migration:status This is the result ![grafik](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/0/08735be240784438ed98f7f7cba3663d7c245b96.png) Just crossed some emails and passwords. Thanks in advance for talking a look at it. ---

Hummm… this doesn’t look good If you try a `php bin/console doctrine:migrations:migrate` Any luck ? ---

If I do, I get EXACTLY the same error above. ---

**[reposted this from the other thread where you had posted. I see my suggestions had already been addressed in this thread…]** For updates I still kinda rely [on this advice](https://mauteam.org/mautic/mautic-admins/mautic-update-how-to-dont-click-that-button). That page includes 3 commands that [Yosu Cadilla](https://mauteam.org/author/yosu-is-admin/) recommends to run before upgrade attempts: php app/console doctrine:migration:migrate php app/console doctrine:schema:update --force php app/console cache:clear Your error has to do with migrations, so have you tried the first? Or probably just do all three. Also make sure you are using the right update package. Also, what database type/version are you on? I had just upgraded from MySQL 5.7.30 to MariaDB 10.3.24 before my upgrade. I think Mautic 3 had some special db requirements. ---

I definitely have to restore the database backup and the files from 2.16.3 and start from scratch. To answer your question, I did upgrade to MariaDB 10.3.24 before upgrading. Crazy stuff… good thing is, this is not a production server, that one is still on 2.16.2 🙂 ---

Good that you’re not on your prod server and have a backup. Let us know how it goes 🙂 ---

Finally had the time to try again… made SURE all files have the right permissions and ended up with EXACTLY the same error. Trying to finally figure out how to update this server somehow… slowly it’s about time to upgrade… Are there somewhere instructions to upgrade from 2.6.13 to 3.0.2 or higher directly? My upgrade\_v3.php seems to only update directly to 3.0.1. Maybe that could offer hope. In the meantime, back to 2.16.3 again. ---

Here are the steps I found on the forum: > **[Upgrade steps](https://docs.mautic.org/en/mautic-3-upgrade/upgrade-steps?_ga=2.223404062.486871931.1595849546-1786381583.1595528670)** > > If you want to know more about all the upgrade steps of the Mautic 3 upgrade process, this is the place to be.The upgrade process consists of multiple steps to make it as robust as possible.

See the pre-flight check: Do you at least have Mautic 2.16.3 installed? So you will need to do 2.16.0 -\> 2.16.3 and then you can upgrade to 3.x. Of course, ensuring that you have a backup that is tested, and ideally at the command line. ---

Finally and HAPPILY I’m on 3.1.2. What was the problem you might wonder? NEVER use an % in your password… Check the RED image above and notice the FIRST and LAST words: > **“The parameter “CcVO5” blablablabla must be defined”** Well, “CcVO5” was the part of the PASSWORD AFTER the % sign. How did I fix it? Went on local.php and changed the % to a 1 and then it just went through like a hot knife through butter. 😉 Happy camper now! ---

You can put your password in quotation marks (") and it use all character as a string. ---

Thanks for the tip. At the time I just decided to change the password and make sure that no % was included, which has been working ever since. It’s good to know that the option exists though. Thanks!
