Upgrading Drupal

Hello,

in my Drupal6 site for user profiles, I used the "content profile" module.
Now I'm trying to migrate the site to Drupal 8, but all the fields of the content profile module are not migrated.
How can I migrate users and content profile fields associated with them?
Thank you very much

Trying to upgrade a Drupal 7 / Postgresql site to new D8 Apache and Postgresql hosts.  Drupal 8 setup and running. 

D8 site is newwiki.example.com is up.

In upgrade site source settings we are using "https://oldwiki.example.com" for source file location and "/mnt/oldpvt" for private file location.  This is a mount point to private files.

Can anyone enlighten me why the D7 administrators rol is migrated next to a new D8 Administrator role and not incorporated in that role?

Hi,

I am having a weird issue that I cannot troubleshoot, I want to update a 8.7.5 install to 8.7.14 prior to a final 8.8.6 update. This is for a production site that I have avoid downtime for. Because of this I tested a method on a dev server that went as follows:

Upload 8.7.14 core/vendor directories as different names, i.e. core8.7.14 and vendor8.7.14

Once uploaded, rename existing 8.7.5 core and vendor files, then rename core8.7.14 to core and vendor8.7.14 to vendor

run update.php

I updated Drupal 8 using Composer. I got this error when logged in to admin. The Drupal version 
"name": "drupal/core",
"version": "8.8.6",
