Hi @Aveeva ,

Can you try running your command like this:

php bin/magento migrate:data vendor/magento/data-migration-tool/etc/opensource-to-opensource/1.9.2.3/config.xml --reset --auto

Hope this helps you!

Hi @Aveeva ,

After settings migration, did you try to access your magento 2 store and checked whether you are able to access frontend and backend successfully or not.

Please check once and if you face any issue in that, try to take backup of core_config_data and do the changes for secure/unsecure url and cookies.

Hope this helps you!

@Nishu Jindal  Backend also works, small permission error, i solved it. Still, data migration not loading, same error.

Any help with this error?

Hi @Aveeva ,

May I know any specific reason for which you are using --auto way instead of manually solving all the errors and warnings manually in map.xml 

I worked with that way and it worked for me smoothly. 

Thanks!

@Nishu Jindal  No any specific reason, magento docs show use --auto, that's what i am using, any better way to run this?

[Nishu Jindal]

Hi @Aveeva , 

You can run the data migration command without --auto or --reset 

And for issues which you will face please refer below link:
