I installed the extension but it does not work.
The errors reported are as follows:

Notice: unserialize (): Unexpected end of serialized data in ... public_html / pub / ub-tool / yii / caching / CCache.php online 108
Notice: unserialize (): Error at offset 0 of 1 bytes in ... / public_html / pub / ub-tool / yii / caching / CCache.php online 108

I ask for your support. Thank you

Hi Andrea,
We wonder which Magento version and the Lite version you’re using? 
We have an outdated script on Github which we no longer maintain. If you use the Lite version at Ubertheme here, please note it has a few drawbacks: 

  • It’s available for Magento 2.0.7 only, and M2.0.7 must be a fresh instance
  • It does not support Nginx server
  • It uses an outdated code base, thus it might lead to unexpected issues. 

So the Lite version is mainly for testing purpose only. We highly recommend you consider moving forward with our Pro version, it will save you pretty much time. 
PS. You can check out a few case studies below to learn more about our Pro version: 

-- Migrating 15,000+ Sales Orders to Magento 2 Using UB Data Migration Pro
-- We did use the Pro version ourself to help – Migrate 382,047 customer entities to Magento 2
-- And this case study as well -- used UB Data Migration Pro to migrate 230,000 products to Magento 2

Hi Andrea,
Please let us know which Lite version you’re using, our old script on Github or the Lite version at Ubertheme here
Depending on specific migration tool you used, we will provide uninstallation guide accordingly.

Hi Andrea,
So you can follow steps below to uninstall our Lite version: 

Step 1: Disable our migration tool by running the CLI command: php -f bin/magento module:disable -c Ubertheme_Ubdatamigration

Step 2: Run the following SQL statements in your M2 database:
DELETE FROM setup_module WHERE module = ‘Ubertheme_Ubdatamigration’;
DROP TABLE IF EXISTS ub_migrate_map_step_2,ub_migrate_map_step_3,ub_migrate_map_step_3_attribute,ub_migrate_map_step_3_attribute_option,ub_migrate_map_step_4,ub_migrate_map_step_5,ub_migrate_map_step_5_product_download,ub_migrate_map_step_5_product_option,ub_migrate_map_step_6,ub_migrate_map_step_6_customer_address,ub_migrate_map_step_7,ub_migrate_map_step_7_invoice,ub_migrate_map_step_7_invoice_item,ub_migrate_map_step_7_order,ub_migrate_map_step_7_order_address,ub_migrate_map_step_7_order_item,ub_migrate_map_step_7_quote,ub_migrate_map_step_7_quote_address,ub_migrate_map_step_7_quote_item,ub_migrate_map_step_8,ub_migrate_map_step_8_downloadable_link_purchased,ub_migrate_map_step_8_rating,ub_migrate_map_step_8_review,ub_migrate_map_step_8_review_summary,ub_migrate_map_step_8_subscriber,ub_migrate_step;

Step 3: Open your Terminal, go to your M2 folder and run below CLI command to clean source code of our tool:
rm -rf app/code/Ubertheme/Ubdatamigration pub/ub-tool/

Hope that helps.
