How to upgrade lite speed webserver from the version 4.0.15 Ente to 4.1RC3-ent?

Guys,

I have referred the following steps as per the discussion with lite speed tech.

=====
Manual update:
cd /usr/local/src
wget http://www.litespeedtech.com/packages/4.0/lsws-4.1RC3-ent-x86_64-linux.tar.gz
tar zxvf lsws-4.1RC3-ent-x86_64-linux.tar.gz
cd lsws-4.1RC3
./install.sh

specify same installation folder as previous one, for example,
/usr/local/lsws
select U(upgrade), just press enter and proceed further. Also restart the service.

It's quite safe. Then in admin console, you can see 4.1RC3, 4.0.15.
switch between version by one-click.

Important : You don't need to rebuild the php with the this latest version of lsws.
