Cannot migrate Data from 1.6 to 2.0

Cannot migrate Data from 1.6 to 2.0

m trying to migrate data from to the latest version of magento but am getting the following error:

    Integrity check failed due to "core_config_data" document does not exist in the destination resource.

The table exists in the magento 2.1.7 database as mgnb_core_config_data

Here is the config.xml info.

        <database host="localhost" name="old_db" user="user"  password="pass"/>
        <database host="localhost" name="new_db" user="user"   password="pass"/>


Re: Cannot migrate Data from 1.6 to 2.0

Hmm, that does look like the correct way to specity a destination prefix. I see many other people talking about this issue. One person here had it a while back: but managed to resolve it by starting again but isn't clear how/why. 


Are changes to the config.xml file definitely taken affect?

If you've found one of my answers useful, please give "Kudos" or "Accept as Solution" as appropriate. Thanks!

Re: Cannot migrate Data from 1.6 to 2.0

Thanks, I removed the database table prefix which got me past that stage. Now I've a problem with crypt keys.


The error I'm getting is [ERROR]: "crypt_key" option is not defined the configuration.


Here is local.xml key




This is what I have on config.xml
