Upgrading Drupal

Greetings,

I am working on a D6 to D8 upgrade for a site that used the D6 core Blog module, along with Taxonomy tags on the Blog Nodes.

I understand that the Blog mod from older D core has become a contrib mod in D8. I have installed that mod into the clean install of D8.

Running the Migrate mod via the UI, no D8 target home is found for the D6 blog.

Is D8's Migrate mod not aware of the old D6 blog mod, so that is why it finds no place to migrate the blog content to in D8?

Hello,
Recently a colleague did an update however he does not remember what modules updated. Anyhow, ever since the update our Marinelli banner does not rotate. Everything works except it does not slide. Another thing we noticed is we are getting an outrageous amount of spam emails coming from a couple of forms we have. We test out the CAPTCHA and seems to be working but somehow we are blaming the update since this happened immediately after.

Any help is greatly appreciated...

Currently Drupal 7.x core updates involve multiple steps and a decent amount of Drupal knowledge.

Currently Drupal 8.x updates can be done with a single command, so long as the website builder has installed the SSH CLI composer utility, a unix command line utility. Once the setup is done it can most of the time be relatively painless. But for many potential Drupal website builders, they do not have command line access to their website server. This problem also means that hosting companies need to be educated about Drupal 8 requirements.

I guess I thought updating Drupal and modules would be relatively easy ... but, alas, it is not to be.
Firstly in updating the modules, I had to have the hosting company disable that mb_string thing. I got the modules to update but then Owl Carousel is throwing error message: Undefined index: settings in theme_owlcarousel_list()

After applying ldap 7.x-2.2 I get:

Fatal error: Call to undefined function drupal_is_https() in mysite\sites\all\modules\ldap\ldap_servers\ldap_servers.module on line 813

Is nobody else getting this?

My drupal installation worked well with composer manager.

After composer manager was abandoned I replaced composer.json to the newest one but most sites then didn't work (i have installed drupal manually by downloading and extracting the files by myself). (and there is also the packagist site which was abonded)

If i require all modules via composer they will be installed into a subfolder contrib, but the site still uses the modules in modules folder (if i remove them the sites doesn't work and it seems that they don't look for modules in the contrib subfolder ...)
