Updating remote servers with new website content
If you plan on upgrading across more than two major releases, you should consider upgrading incrementally to avoid potential conflicts and minimize the risks of database damage.For example, if you plan on upgrading from 2.5 to 4.7.3, upgrade to 2.7 first, followed by 2.9, then 3.1, and so on. Older versions of Word Press can be downloaded from the release archive.I have then made changes in a single file locally which shows changes made in the Local Git Repository opened in Source Tree.
Remember, if you do encounter problems, re-read the Instructions below to insure you've followed the proper procedures and consult Troubleshooting: Common Installation Problems.
You could also have multiple content management servers, depending on your content editing needs.
Synchronize all servers to a single reliable time source, for example, by means of the Network Time Protocol (NTP).
Then create or import a database, upload files, and add DNS records.
Start by installing a web server, database, and PHP - a popular combination which is commonly referred to as the LAMP stack (Linux, Apache, My SQL, and PHP).
