Converting to Drupal

I apologize if this is an incorrect approach. I have been using Drupal here and there for a number of years, pretty new to the forum...

I am new to Drupal. I have a working webapp in PHP/MySQL which I am trying to port to Drupal. Here is my problem:

In the webapp, I have a table called Patients with a DoB (Date of Birth) field. The input form takes in information as "Age" in years and months, and inputs an approximate DoB by subtracting from current date (This is because most of the patients, where this is used, are not aware of their DoB).

When migrating Drupal 7 - Drupal 8, it was discovered that views were not migrated.
I tried these modules:
https://www.drupal.org/project/views_d8_upgrade
https://www.drupal.org/project/view_migration
But the modules turned out to be outdated and inoperative.

Is there a solution for automatic migration of views?

Hi 

How can I migrate the forms in the existing site (source: SQL) to webforms drupal 8.

Any pointers will be helpful.

Hi,

I have a small website about my company and I would like to convert it into Drupal 8 website, for that I would like to make sure if it is possible to have a live map where it will show me the track used by every single driver in my company (Google map or whatever any other map).

It is like having a Map and a blue line indicating the live distance between currently being traveled by a car from point A to Point B using the driver's phone built-in GPS.

I need something similar to this GIF Image:

I am trying to migrate a Drupal 7 site to Drupal 8, however, I keep getting this error;

Resolve all issues below to continue the upgrade. The d6_library_transaction plugin must define the source_module property.

So I followed the recommended steps just as it says but the error above says something about plugin needing to be defined.
