All depends on your requirements.
Our procedure is to load a copy to a Dev folder that can only be seen by admins and test through the client and on desktop versions, then roll out to a UAT group over whichever client you use, then to go live once we're sure performance is consistent and the data is serving it's correct purpose.
Depends how many users you have, what your system set up is, where your data is coming from, who needs to validate each aspect etc.
