Upgrade from V7.02.07 fail

Hi, i don't want to open e new thread so i think that here is the right place to post my problem.
I try to make upgrade from 7.02 to 9 and i have an error at Database Settings and Server Paths - Please enter your MySQL database access settings.
Error is this: There was an error while processing your request
I chek 3 time all dates and i don't find nothing wrong. Problem can be because my site is on a folder and not direct in local host something like public_htm/sitefolder in cpanel. Can be problem from there? i second domain on host.

Please if you can help me to go on next steps!

There are too many quirks and anomalies for the upgrade to work consistently for each and every individual. I found that the mySQL table changes were too critical, and in the end I rebuilt my data the long way, by reconstructing CSV files by hand. Thankfully, there are not too many tables to contend with, the keys ones for me were users, articles, comments, ratings and custom-pages. The Forums tables were very difficult, so I left them - to have a think about for another day.

That's good news

I apologise for the bad experience in upgrading this. I have a rough model of remote update/upgrade started that I will announce Babylon forward.

Same here. I had major issues and I'm usually really good with research to find problems however this time I wasn't so successfull with the exception of resolving one half of the error on my own. One issue being the version of PHP I was running, so I updated from PHP 5.1 to version PHP 7.1 which removed half of the errors. What remains is the following error on the install.php page (www.gojuryu.net).

Warning: session_start(): open(/var/php_sessions/sess_6d83fcf44e60f61ae3fa06b7c5bd1cb7, O_RDWR) failed: No such file or directory (2) in /hermes/bosnaweb17a/b609/ipw.gojuryun/public_html/includes/classes/PHPFusion/Installer/Install.core.inc on line 123

I have no idea what this

You can try the latest Andromeda, https://github.com/PHPFusion/PHPFusion ( 9.03 )

If I download this from github i receive a download that is abnormally small (Andromeda is 8mb in ZIP format) and has no files in some of the directories (blog for example). What can be wrong is this intended?

You must install Git https://git-scm.com/downloads
after installation open cmd/terminal and run this command

git clone --recursive https://github.com/PHPFusion/PHPFusion.git php-fusion

Please read README https://github.com/PHPFusion/PHPFusion#new-changes-about-submodules-and-git-management-of-core-infusions-ci

I assume that "clone or download" is not to be taken serious on github?! I download the dir now and it is 139MB (in total commander) with a ".git" dir of 117MB, i assume it is needed so i leave it there. Anyway, much bigger than the v9.00 here to download. Thanks for the tip!

All .git files can be deleted.

"Clone or download" works too but we have few infusions in separate repositories. And in the main repository they are linked as submodules. This is why all files are not downloaded after clicking on "Clone or download"

I try a new upgrade to 9.03.30 this time. Everything was work fine but now on new version content from articles, news, forum and other don't show, i am look in database after upgrade and i see new table that are emty and the old table are there with content from articles from news and others. What i must to do for have content in new site at 9.03.30 from my v7?

I had a similar situation when I made my first attempt to upgrade from version 7 to pf-8. My problem was choosing the wrong php version. That was a year ago and now I don’t remember the details. I rolled back to version 7, and only later from the second attempt I managed to upgrade well to the new version 8. This time I used another version of php. Perhaps to upgrade to pf-9, the php version does not play an important role, I don’t know this. What version of php are you using to upgrade?

Upgrade site with PHP 5.6 after successful upgrade change PHP back to 7.4.
V9 works also on PHP 5.6 but sometime you can get errors that's reason why we changed min. PHP to 7.0.
