Installing NGINX Plus might change the behavior of your NGINX server if you are using any third‑party modules compiled from source, because NGINX Plus is distributed as a binary with a predetermined set of modules built in (listed in the NGINX Plus Technical Specifications). You can, however, load third‑party modules dynamically into NGINX Plus at runtime. We recommend checking for any feature differences between your current version of NGINX and the current NGINX Plus release before upgrading.
The way you perform the NGINX Plus installation depends on your current deployment. We recommend that before any NGINX or NGINX Plus upgrade, you always back up your existing NGINX configuration files.

yum
package manager to install NGINX Open Source, run theyum
swap

apt-get
package manager to install NGINX Open Source, simply run theapt-get
install
command to install NGINX Plus. - If you installed NGINX Open Source from source, you need to stop the NGINX service manually, remove the existing NGINX binary from your system, and then use your operating system’s package manager to install NGINX Plus.
