Upgrading Drupal

I have upgraded my site from D 8.5.3 to 8.5.8.

Looks everything is ok.

May I upgrade now directly to 8.6.2 ?

Do I need to upgrade to 8.6.2 ?

If not, should I upgrade to 8.6.2 ?

If yes, why?

Thank you

Updating from 7.59 to 7.60, when i start the update.php I did get this failure

I'm a fairly new Drupal user. I have one server running a couple of sites under Drupal 8 and another server running Drupal 7, both distributions installed as tarballs. I successfully managed to install Composer and use it to update the Drupal 8 core (using Composerize-Drupal), but I have not yet found any good instructions on how to convert an existing D7 site to be managed with Composer. Can this be done; is it worth doing; and, if so, how do I go about it?

With Composer, I never was able to upgrade my Drupal 8.3.9 to 8.4 due to composer error and any solution doesn't work for me...

Ex. I run: composer update --with-dependencies drupal/core:

Dear all,

i used for privat over years a drupal 6 with the module fastgallery with many folders and thousand pictures on the drupal 6.

To be more secure and to support with the Theme also mobile devices i made on the same webserver a Drupal 8 installation.

In Drupal 8 Fastgallery is non available, so i setup an image gallery, it works... more or less the same as Fastgallery.

No my question, how could i import in Drupal 8 easy all pictures from Drupal 6 fast gallery, without downloading all pictures and manually upload again in Drupal 8 ...

Any idea?

I upgraded my site from Drupal 7 to Drupal 8.6.2, and now have some errors I cannot track down or solve.
