changing working color space requires re-calibration?

I calibrated my monitor and is using sRGB as working space in photoshop cs2.

If I open an adobeRGB tagged photo, photoshop says profile mismatch. If I choose to convert adobeRGB to sRGB, would some colors get clipped by the smaller sRGB space?

Suppose I want my working space to be adobeRGB, what are all the color management related things I need to change, in addition to choosing adobeRGB as the working space in photoshop? Do I need to change the monitor calibration process?

I don’t see any parameters in the calibration software (coloreyes display pro) related to the intended working space so I’m guessing the answer is no.

Short answer: monitor calibration doesn’t depend on
working spaces.

For your monitor calibration you are free to choose:
a) min.luminance, black point, typically below 0.3cd/m2.
b) max.luminance, typically 100cd/m2 in a dimmed room.
c) gamma, normally gamma=2.2.
d) white point: 6500K or 5000K or something between.

Despite all color management, the working spaces sRGB
and aRGB (AdobeRGB) with white points D65 (6500K) can
be shown with 6500K or more yellowish down to 5000K.
This color shift is not corrected by color management.

Now you can use any RGB working space, preferably sRGB
or aRGB, but some color ranges of aRGB are out-of-gamut
in sRGB and in MonitorRGB, which is mostly near to sRGB.

Therefore all color editing in aRGB, as visualized by
the monitor, is occasionally doubtful.
New practical applications can be found here – mainly
for final results in CMYK:

Working space is a completely separate issue from monitor calibration.

The "color profile mismatch" message you get is a configurable warning that you are opening an image that does not match your working space. You may convert to your working space or not, without any concern about the accuracy of the colors.

In my experience, converting a photograph from Adobe RGB to sRGB seldom results in clipped colors.
