How can I upgrade or change to a specific version of Litespeed?

Introduction

Utilizing LiteSpeeds LSUP script, you can upgrade/change to a specific version of LiteSpeed.

Running lsup without a parameter will automatically upgrade your installation of LiteSpeed Web Server to the latest stable release.

/usr/local/lsws/admin/misc/lsup.sh

The following parameters are available for use with lsup.

-v: The -v parameter, followed by a version number, allows you to specify the version to install.
```
/usr/local/lsws/admin/misc/lsup.sh -v 6.0
```
-b: The -b parameter designates a build number. All versions start from build '0'. lsup will automatically upgrade to the latest build of the designated version if -b is not set.
```
/usr/local/lsws/admin/misc/lsup.sh -v 6.0 -b 2
```
Please note that this option is only available for LSWS versions 5.0 and higher.
-f: The -f parameter forces lsup to install the latest edge build.
```
/usr/local/lsws/admin/misc/lsup.sh -f
```
