The table "{{core_website}}" for active record class "Mage1Website" cannot be found in the database

[CharanjeetE]

I am migrating magento 1.9.3.7 to magento 2.3.0 but getting this error. Please suggest me how can I overcome this issue. I am not using any database prefixes in both m1 or m2.

Hi @CharanjeetE ,

It's pity that we no longer maintain the outdated script here at Github, and replaced it with a newer Pro version.

Meanwhile, we've just replied to you via the ticket you submitted at Ubertheme here. Please follow up further with us there.

Regards,
Ubertheme team
