Magento – Magento Migration Redirects to the old Server

Just repeat your migration - it has clearly gone wrong

cd /domains/example.com/http
wget sys.sonassi.com/mage-dbdump.sh
bash mage-dbdump.sh
tar cvfz ../http.tgz . --exclude=var/log --exclude=var/session --exclude=var/cache --exclude=var/*port

Then transfer that file to the new server, extract it

tar xvfz http.tgz

Edit the ./app/etc/local.xml to reflect the new DB details

Then restore the DB

bash mage-dbdump.sh --restore

There's good documented procedure that's a little more verbose than the above here.

Or automate the process

We've also got an automated script to do quick migrations (without media etc.)

wget sys.sonassi.com/mage-bundle.sh
bash mage-bundle.sh

This will dump the DB and tar up the document root (excluding tmp files, reports, errors, media, archvies, static content etc.) - for a quick migration.

This is really aimed towards doing dev/test migrations (or backups); but you can use this to get a base of the site over; then supplement the missing files with an rsync from the other machine, eg.

/usr/bin/rsync -par /domains/example.com/http/ exampleuser@111.111.111.111:/domains/example.com/http/ --delete --exclude=var/log --exclude=var/session --exclude=var/cache --exclude=var/report --exclude=app/etc/local.xml

Clean up your permissions

And always, check and clean up your permissions, replace www-data with your respective user/group

chown -R www-data:www-data/home/sonassi/public_html
find /home/sonassi/public_html -type d -exec chmod 775 {} \;
find /home/sonassi/public_html -type f -exec chmod 664 {} \;

Or again, read this for a more permanent, sophisticated solution.

If you are facing this problem, You have to commment the line in .htaccess file.

#    RewriteBase /magento/

or

Set the RewriteBase in .htaccess file.

RewriteBase /

I have tested this in Magento 2
