Upgrade CB 1.3 to CB 1.4

Hello, I am a French user

My site works with CB 1.3, and I want upgrade into CB 1.4.

Should I follow the steps in the readme-upgrade.txt or before innstaller CB 1.3.1

1) Install new CB component (com_comprofiler.zip) from
your CB 1.4 distribution package.
There is no need to previously uninstall component - code will upgrade
automatically.
2) Install new CB Login module (mod_cblogin.zip package)
from your CB 1.4 distribution package.
3) Install new CB Workflow module (mod_comprofilerModerator.zip package)
from your CB 1.4 distibution package.
4) Install new CB Online module (mod_comprofilerOnline.zip package)
from your CB 1.4 distribution package.
5) Run CB Tool checks on CB database.
6) Done!

Thanks
