Something to consider is that there *are* areas where libreoffice is deficient.
It's not uncommon for businesses to have a terrifying amount of embedded visual basic and incredibly elaborate excel macros, I wouldn't be surprised if the (possibly theoretical) suit literally can't get their work done because they don't have access to their scripts and macros that some secretary wrote in 1999. Any migration which messes with office, if you want it to be successful you really need a serious period of testing where you grab up as many business-essential documents as you can and identifying scripts and macros which may become problems, then rewriting them in LO compatible way (LO has scripting, it's just not *literally* vbscript). It has a basic dialect so translation shouldn't necessarily be hard, just time consuming.
