@asmecher i have tried upgrade 2.3.5 to 3.1, and before any upgrade process i figure that i should do these steps below:
step 1: upgrade from 2.3.5 to 2.4.8
step 2: upgrade from 2.4.8 to 3.1

but when i want run step 1 on upgrade web process - i faced bad problem, system return “ERROR: Upgrade failed: DB: Table ‘ojs.article_event_log’ doesn’t exist”

for more information i put output of this command: “php tools/upgrade.php checkCode”
version: 2.4.8.0
Database version: 2.3.5.0
Latest version: 3.1.0.1
Database version is older than code version
Run “tools/upgrade.php upgrade” to update

and after Run “tools/upgrade.php upgrade” to update return this error : “Upgrade failed: DB: Table ‘ojs.article_event_log’ doesn’t exist”

Hi @mbabaei

Is this a very first attempt of upgrade in such database? It looks like that this DB had a previous incomplete upgrade attempt.
Please, if possible, restore your DB backup and run upgrade again to double check this issue persists.
