Answer 1

If you are choosing data-migration tool of magento.

Go to your magento2->vendor->magento->data migration tool.

Hope you done the config.xml setup.Inside config.xml change class-map.xml.dist to class-map.xml.

Then choose the class-map.xml.dist file change to class-map.xml file and remove the class which is not find in new.

example : <rename<from>megamenu/category_attribute_source_type_style</from> <to></to> </rename>

Answer 2

Your issue happens for some category attributes which are related to your Magento 1 Porto Theme.

In magento1, you have some category attributes which using Proto theme some class as Source model. As you don't have the same theme existing at my your magento2 theme and Magento 1 and Magento 2 source model mapping different and Magento2 full page class source model as source model.

Example;

  'display_mode' => [
                        'type' => 'varchar',
                        'label' => 'Display Mode',
                        'input' => 'select',
                        'source' => \Magento\Catalog\Model\Category\Attribute\Source\Mode::class,
                        'required' => false,
                        'sort_order' => 10,
                        'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
                        'group' => 'Display Settings',
                    ]

See Magento2: Mapping 'source' => \Magento\Catalog\Model\Category\Attribute\Source\Mode::class.

Where magento 1 is follow: 'source' => 'catalog/category_attribute_source_mode', like

Solution:

In this case, there are two solutions:

1. Ignore all attribute which is related with the proto theme like at eav-attribute-groups.xml

<group name="ignore">
  <attribute type="catalog_category">[ATTRIBUTE_CODE]</attribute>
</group>

See how to ignore an attribute during data migration check out the article https://magento.stackexchange.com/a/170907/4564

2. You have the convert the code of porto/category_attribute_source_tab_mode class to magento 2 stucture.
