How to update Julia in ssh clusters

I'm working as a PhD student in a lab with ssh clusters, I have the access to connect to each one of them (there's no queue system, as it is a small lab, hence, as long as someone is not using a lot of cores in each computer I can run my programs on them).

Currently the lab doesn't have a cluster administrator so its maintenance is in the hands of two researchers with computer knowledge. Currently, the clusters have a very old version of Julia (0.5.1) and I need an update in order to work; however, one of the two researchers in charge told me that it will require a very large amount of time and stopping all current process in order to update Julia, so he is unwilling to make the update on the clusters.

Is there a way that I can update the Julia version on the clusters all by myself? Without interrupting nor canceling any of the current processes?

I believe non of the current processes are being run with Julia, as I am the only one in the lab who works with it. The languages being used for these processes are C, C++ and Fortran.

Julia does not need to be installed system-wide to be used. In fact on all OSes - Linux, Mac and Windows - the Julia distribution is portable and self-contained.

So, the easiest way to get this is to use juliaup to install julia on all the nodes, and use it to manage all the julia versions you need.
