unable to migrate site from one server to another I have to migrate as site from one server to another. I exported the databaseusing MySqladmin which I also used to import the db on the new server, I copied all files over but I keep getting errors like: 
Fatal error: require_once(): Failed opening required '/home/quaaout/public_html/drupal-7.43/sites/all/modules/rules/modules/events.inc' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/quaaout/public_html/drupal-7.43/sites/all/modules/rules/rules.module on line 9

so I tried loading the latest drupal 7 core 7.43 but I get exactly the same. I then tried to erase that one module rules but I got the error for the next, I deleted and the same error would popup for modules rules, apps, contentanalysis,kwresearch (which I deleted one after the other) but after the last one I stopped and thought there must be another way to get rid of this error, but how? Please advise!
Thanks!

EDIT1

And then since I updated my db version, I tried to call update.php but that won't work i.e. the server returns nothing, I get an empty page in firefox and Chrome says: The  page isn’t working

EDIT2

What I also tried is: wget --ftp-user=USER --ftp-password=PASS -r ftp://ftp.myolddomain.com/ . to download the complete site the new host but I still get Fatal error: require_once(): Failed opening required '/home/quaaout/public_html/ftp.quaaoutlodge.com/sites/all/modules/rules/modules/events.inc' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/quaaout/public_html/ftp.quaaoutlodge.com/sites/all/modules/rules/rules.module on line 9 when trying to access the page through the new domain...

EDIT 3

Okay, seems like the initial wget command didn not catch all the files and I had to re-copy the sites/all/modules/ and sites/all/themes. Seems like I've caught everything now. I'm not sure why this would not have worked initially.
Manoj Bisht, please return and add your comment as answer to get the credit you deserve, after all, I only started checking for the files within the modules &amp; themes directories after you told me to...
Have you tried backup migrate?

Make sure you have a vanilla drupal install working perfectly, then copy the sites/all folder from your first server, enable backup migrate and then restore the backup from the first server. 

Basically, it will be a lot easier to troubleshoot if you're on a vanilla install and backup migrate is perfect for this.
