Upgrading Drupal

Hello Drupal-ers,

I'm looking to upgrade several sites from Drupal 6 to 7.
After some research, I have come across two solutions, some use the Migrate module for less complicated sites, while some use the more manual method as stated in the Upgrade.txt documentation.

I believe the Migrate module is more suitable for simpler sites and is a little bit more straightforward. While the manual method essentially works around the /sites directory.

I have one Drupal 5 site. I need to upgrade site to Drupal 7.
On my analysis I found that we can do it in two ways:
1. Drush update to latest version of 5 and then to Drupal 6 and then Drupal 7. But its a long way.
2. Using migrated2d module or feed module to migrate data to fresh Drupal 7 installation.

Can someone suggest better solutions and also any references ?

Also is feed module is available for Drupal 5 ?

I was upgrading a theme on one of my test sites (Drupal 8) like this:

drush up mayo

Something went ... wrong. I'm new to drush, so I can't say much more than that. It failed and my site started acting like I didn't have any themes installed.

I first tried to back out of it by copying the original theme files back out of drush backups, but my site failed to recognize that the files were there. Even after multiple "drush cr". I then backed out of it by setting the default theme to Bartik via drush, and then installed the theme like this:

I have a Drupal 6 app that I want to upgrade to 8.1.1 so I'm following the instructions at Drupal.org.
Drupal core 8.1.1, php 5.6.19, ubuntu 14.04

I first try drush using the latest version available (8.0.5) but the module is not found when I attempt to run drush migrate-upgrade. I gave up on it since there seems to be a problem.

I have changed a module setting of a drupal site. which i did was enable page maker and cTool modules.

Then after that at the beginning of each page following error message dispalys! (Drupal Theme Aqua Mania)

"user warning: Table 'Math_home.delegator_handlers' doesn't exist query: SELECT * FROM delegator_handlers WHERE task = 'node_view' AND subtask = '' in /var/www/vhost/math/host/sites/all/modules/ctools/includes/export.inc on line 105."

How can I remove this error?
