Sometimes its better to have a change, and moving from one OS to another would seem the perfect oppourtunity, however saying that, chaning to a different shell means there will be different syntax to commands and may make people make mistakes which could cause problems.

Similarly certain scripts might run under the tcsh shell which wont work with bash and you wont find out until you run them and it may cause harm to your server depending on what the script does. (worst case scenario)

I would suggest you try a test user on a test server using a new shell to see if there are any adverse effects when running day to day admin activities, if it works ok then its up to you to choose to stick with tcsh or try a new shell which may provide new functionality and make admin activities easy.

includes file name completeion, history command editing, file name colouring to distinguish between files directories links etc.

It's not that some tcsh scripts might not work in bash... it's that they definitely won't. They're not the same language. Even tcsh statements which bash doesn't complain about probably won't do what you expect since the language constructs are very different.
