Will migrating website to new server create problems?

Hi Mark,
All depends!

If you are keeping the same URL when migrating there should be no issues.
Depending on how you do it, if people make edits during the first 48hours it may be saved on the old server not the new one.
There’s a way they can do it where you set up on the new server and then get the DNS records pointing to the new one from the old one. But there’s still a lag as the internet updates itself.

If you are changing URLs you will need to let me know for the app. And…
When you do the database move, there’s a couple of queries to update the database that can be done to smoothly migrate WordPress to the new URL. If you have access to PHPmyAdmin you can do them…

UPDATE wp_options SET option_value = replace(option_value, "http://www.oldsiteurl.com", "http://www.newsiteurl.com") WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET guid = REPLACE (guid, "http://www.oldsiteurl.com", "http://www.newsiteurl.com");
UPDATE wp_posts SET post_content = REPLACE (post_content, "http://www.oldsiteurl.com", "http://www.newsiteurl.com");
UPDATE wp_postmeta SET meta_value = REPLACE (meta_value, "http://www.oldsiteurl.com","http://www.newsiteurl.com");

If the URL has changed you will need to update your Google API key restrictions as well *newsiteurl.com/*

Hope that helps – don’t know how techy you are! If you need to hire me to do the migration, get in touch!!!
