Hello everyone,
I am experiencing with data migration. Created the
vendor/magento/data-migration-tool/etc/ce-to-ce/1.9.1.0/config.xml
and ran it. As expected several tables did not work because they were not mapped yet. So, let's edit the
vendor/magento/data-migration-tool/etc/ce-to-ce/1.9.1.0/map.xml
for every error:
Source documents are missing or not mapped: amasty_methods_visibility,assignorder_history,banners,banners_store,
I added:
    <source>
        <document_rules>
<!--custom ignored documents -->
            <ignore>
                <document>amasty_methods_visibility</document>
            </ignore>
            <ignore>
                <document>assignorder_history</document>
            </ignore>
            <ignore>
                <document>banners</document>
            </ignore>And for every missing field:
Source fields are missing or not mapped. Document: sales_flat_quote_address. Fields: fee_amount,base_fee_amount,card_info
I added
<!--Here are my custom ignored fields-->
                <field>sales_flat_quote.onestepcheckout_customerfeedback</field>
            </ignore>
	    <ignore>
                <field>sales_flat_quote_address.fee_amount</field>
            </ignore>
	    <ignore>
                <field>sales_flat_quote_address.base_fee_amount</field>
            </ignore>
	    <ignore>
                <field>sales_flat_quote_address.card_info</field>
            </ignore>
<!--End of custom ignored fields-->Reran the sync, same errors appear and I get a
[Migration\Exception] Integrity Check failed
Solved! Go to Solution.
Nevermind,
silly enough did not see the map.xml.dist in the config file.
Next step
I don't know much about Technology. But i use this tool and feel it very effectively. This tool allows you to migrate your Magento to the latest version with ease. You can explore it via the website: https://goo.gl/URTUZ9. It will take some hours to finish all. Good luck!
