Steps to upgrade jupyterlab

Hi,

I am currently using below version of jupyter…I want to upgrade this…we are having jupyter hub as well for our all users. How to upgrade jupyter lab to all the users within one server…or else simply one upgrade from my servers would serve all the users the upgraded verion?

jupyter --version
jupyter core : 4.6.3
jupyter-notebook : 6.0.3
qtconsole : 4.7.5
ipython : 7.16.1
ipykernel : 5.3.2
jupyter client : 6.1.6
jupyter lab : 2.2.2
nbconvert : 5.6.1
ipywidgets : 7.5.1
nbformat : 5.0.7
traitlets : 4.3.3

Also after upgrade I am getting below warnings,
