Errors when upgrade WSO2 IS as KM and APIs are not migrated - wso2

Question

I tried to upgrade WSO2 IS as KM from 5.6.0 to 5.7.0 and API Manager from 2.5.0 to 2.6.0 in corresponding with instructions:
https://docs.wso2.com/display/AM260/Upgrading+from+the+Previous+Release+when+WSO2+IS+is+the+Key+Manager
https://docs.wso2.com/display/IS570/Upgrading+from+the+Previous+Release
https://docs.wso2.com/display/AM260/Upgrading+from+the+Previous+Release
In instructions there is no mention that i need to import SQl script again to DB apimgt from /dbscripts/apimgt/mysql.sql, cause 5.7.0 IS as KM has more tables in that DB than 5.6.0 version.
During upgrade of IS i have errors in logs:
ERROR {org.wso2.carbon.is.migration.service.SchemaMigrator} - Error occurred while executing SQL script for migrating database

Despite on errors IS is launched, after i launched API-M without errors, but my APIs are not migrated.
I use MariaDB 5.5.
What is the problem with IS and why APIs dont migrated?

"So i shouldn't do Steps from 2.1 to 2.4, yes? But what with errors that i have during upgrade of IS?"
That means, didn't you do the steps 2.1 to 2.4 in https://docs.wso2.com/display/AM260/Upgrading+from+the+Previous+Release#c130adc044364015ae336f584909e3ac?
If you have already followed the steps mentioned in https://docs.wso2.com/display/AM260/Upgrading+from+the+Previous+Release+when+WSO2+IS+is+the+Key+Manager#250, then you need to skip only the 2.4 step in https://docs.wso2.com/display/AM260/Upgrading+from+the+Previous+Release#c130adc044364015ae336f584909e3ac.
Also please make sure that you have given the versions correctly in the migration-config.yaml file as below.
migrationEnable: "true"
currentVersion: "5.6.0"
migrateVersion: "5.7.0"
Note: You do not need to create tables manually.
