It is for [login to view URL] For this, we need an experienced Server Admin who will migrate/copy the website from our Live Host onto the Staging Server and onto the Backup.

It contains all the iterations and is perfect for initial testing of new features. This product is then uploaded to Git and then cloned to a development server. Development & QA server: Once the website is developed and approved by leads, the project is passed on to a Development/QA server. This server is accessible by the whole QA team that can test, fix, and point out mistakes that the developers may have missed. All top companies use a development server to test their website/app before take it live. Staging Sites/Servers: These are the bridge between development servers. They are not public and only those that have access to the staging sites can access them. After developers add new features to the product/website, they are moved to the staging servers so that the internal teams can test them. This also ensures that all remaining errors are removed. Production/Live Website. This is the final version of the website that is available to the public. It can also be indexed by search engines. It is important that the website has no errors and all areas of concern are carefully checked before the website is moved to the live server. I will need to fully see the work (the website working completely) for quality control.
