Although it’s tempting to install whatever seems convenient at the moment, it’s also important to look to see how a new device fits in with existing network equipment. Ideally, you should upgrade all of the same kind of network components all at once.
A standardized network with consistent cabling, identical servers, similar desktop computers, and standardized, regularly updated software saves time.
An inconsistent network causes aggravation both when deploying and when troubleshooting, because each component needs to be addressed individually. An inconsistent network is more likely to turn up incompatibilities, which must be remedied on a component-by-component basis.
