How to use "conda update -n base conda" properly

I have two very simple questions regarding updating conda. I.e. when updating one of my environments with conda update --all, I get a warning

==> WARNING: A newer version of conda exists. <==
  current version: xyz1
  latest version: xyz2

Please update conda by running

    $ conda update -n base conda

My setup comprises a base environment and two actual work environments, say, (env1) and (env2). The latter two environments are kept up to date with conda update --all, issued within each of those environments. The base environment was only generated in the installation process of Anaconda.

Question 1: Should one run conda update -n base conda on the command line of the OS (linux) prior to activating any environment? Or should one activate a particular environment? Or is the environment out of which this command is issued irrelevant?

Question 2: After running conda update -n base conda from out of whatever environment, as determined by the answer to question 1, would a subsequent conda update --all issued within one of my two work environments (env1,2) install or update any additional stuff, only as a consequence of the previous conda update -n base conda?

(PS.: I find many questions on stackoverflow regarding conda update conda, but they don't seem to cover this one.)

Q1: -n explicitly specifies environment - this command will run in any environment and even if you have no environment active.

Q2: In all but very few cases updating conda will not affect the packages ought to be installed in other environments. conda plays the role as a package manager. The packages are pulled from an index that is independent of conda's version.

you deal with conda like any other package manager you update it in base environment by conda update -n base conda

conda update --all

is meant to update all packages in the activated environment check this
