Upgrade from 6.1.8 to 9.1.8

[preacherrichd]

I have data on Espocrm 6.1.8 version. I am not able to log in. So I cannot update it to 9.1.8.

is there a way to import the data from 6.1.8 into 9.1.8? I am assuming I cannot jdo a MySQL dump because the database s probably are the not same. Any resolution?

You need to fix your 6.1.8 and upgrade it to 9.1.8.
- Enable Debug mode: https://docs.espocrm.com/administrat...ng/#debug-mode.
- Reproduce the error.
- Provide part of the log with this error. EspoCRM log files are located in {ESPO_ROOT}/data/logs/ directory. Most errors are logger there.

Another option: you can create clean 6.1.8 and move dump.sql, /custom and /data there. And only then update to 9.1.8. This is described in detail here: https://forum.espocrm.com/forum/inst...345#post105345.

Downgrade PHP version to one that was the latest at the moment 6.1.0 was released. Then upgrade to a few version up using the upgrade command. Then, upgrade PHP, and then upgrade Espo again. PHP version must be one that is compatible with Espo version.

v6.1.0 – supports PHP v8.0. With this PHP, you can upgrade up to Espo v8.0 (inclusively). Then, upgrade PHP to v8.2. With this PHP, you can upgrade to Espo v9.1. Then, you can upgrade PHP to v8.4.

This is the error I keep getting:
ERROR: Uncaught Exception Espo\Core\Exceptions\Error: "Bad data stored in file 'data/cache/application/webhooks.php'." at /chroot/home/creating/creatingfutures.org/html/leads/application/Espo/Core/Utils/File/Manager.php line 234 {"exception":"[object] (Espo\\Core\\Exceptions\\Error(code: 500): Bad data stored in file 'data/cache/application/webhooks.php'. at /chroot/home/creating/creatingfutures.org/html/leads/application/Espo/Core/Utils/File/Manager.php:234)"} []

Delete data/cache manually.

One of the errors:
This occurs when i try to login using one of my admin usernames. After I get the error to login I then go to recovery password and I get another error.

I finally was able to log in by changing php to 7.4.33. it appears there was a delay in the php downgrade.

Even though I can log in there are bugs, cannot save items. Keep getting this error message:
Error 500: Bad data stored in file 'data/cache/aoolication/webhooks.php'.

So now that I can get into espocrm 6.1.8 is there anyway to export the data into a file. Install 9.1.8 and import data from 6.1.8.
Because I am getting the error message I am concerned that if i do several incremental upgrades at some point I may lose my data.

I see I can import data as csv but I do not see anyway to export data via csv.

These are not bugs. Likely file permissions problem. You need to delete data/cache manually, and make sure file permissions are fine.

You can dump the whole database and backup the 'data' and 'custom' folders.

But I'd recommend to upgrade the normal way.

[preacherrichd]

I deleted cache. No longer get the Error 500. But if I do any edits in a users profile and try to save it, get message user already exists. When I close out the user profile get the warning not saved. So no way to save info. I do not see how permissions could have changed since no changes to the files. Where can I find what the permissions should be and what folders/files would be related to this issue.

Regarding updgrading. Can I upgrade from 6.1.8 to latest of version 7, then to latest of version 8, then latest of version 9, or do I have to go from subversion to subversion.

First you will have to use the Legacy way to upgrade: https://docs.espocrm.com/administrat...way-to-upgrade. It all depends on the possible upgrade files: https://www.espocrm.com/download/upgrades/ and they will mostly be "from subversion to subversion".
To verify that your instance is running successfully after each Upgrade, you can make Rebuild from UI (or by CLI):

php rebuild.php

You can continue to upgrade by a similar way, but periodically from version to version you can check root folder for the presence of the command.php file. Once this file appears, you can switch to the most convenient method by CLI:

php command.php upgrade
