I have changed to `Julia 1.6.0`. My `Jupyter` kernel is also 1.6.0. But when I try to open some (old) `ipnyb` file, my kernel dies.  
What shall I do? Shall I build an old (compatible) kernel? If yes, how can I do it?

I solved this problem.  
In the directory where is the `ipynb` file I did `activate .` and then `instantiate`.  
After that I did `build IJulia` and after:  
`using IJulia`  
`notebook()`  
And it worked with the kernel 1.6.0.

You need to re-build IJulia if you move install/move the Julia executable to a new location: [Installation · IJulia](https://julialang.github.io/IJulia.jl/stable/manual/installation/#Updating-Julia-and-IJulia)
