Search sharepoint 2019 site collection in 2010 search

Hi, we have our production environment in sharepoint 2010 and in the process of migrating to 2019.

We have a web application created in 2019 and copied the policy documents from 2010 site to 2019 site.

I would like crawl the content of 2019 in 2010.

Is it possible? When I did that, it is saying 'Access is denied. Verify that either the Default Content Access Account
has access to this repository...' I made sure that default content access account is the site collection administrator for the 2019 site collection still the same error.

Is it possible to crawl 2019 site collection in 2010?
