Upgrading Drupal

Hi

Just set up a separate clean D8 Install ready to receive prior D7 site.
There's data I'd like in the D8 site from the old D7 site.

Added the missing module that I'd like to keep (Superfish).

Run [www...siteurl]/upgrade from the browser
Get the Welcome to the Upgrade page
Select "Continue"

Get Upgrade page & put in all DB, user settings from current D7 site, including site prefix.
Select "Review Upgrade" button

Hi All!
I've just joined to this community and I hope that you can help me! :)
I have a Drupal 6 site with some modules that are not available for Drupal 8 (contemplate for example).
Drupal 8 should be quite different than 6 so I'd like to ask, what is the best approach to upgrade from 6 to 8?
thanks!

I have just installed the 8.0.1 and want to try the Migrate and Migrate Drupal core extensions. But when I select them and click install they are not installed. What do I wrong?

Thanks,
Fred

I updated my core files but when I now go to the site every page are empty. When I put error reporting on, text is "
Fatal error: Call to undefined function user_access() in /home/www/sites/all/modules/admin_language/admin_language.module on line 558"

I checked that admin language module status is 1 in database.

How can I solve problem and get my site live again?

I 've tried to run an update for drupal 7 and ran into problems. My site wouldn't load. I get an error message:

Please suggest a module that can display total no. of anonymous and authenticated users visiting the site. The count should increment by one per visit. The counter module and visitor module available are incrementing twice, once during login and once during logout for authenticated users. Please suggest a suitable module which will count exact no of visitors by incrementing the count by one per visit
