Please help:
I have purchased and moved into a new house. The last owners were not the purchasers or installers of the pre-existing wired sound system and do not have the details. The house is 3 stories and 4000m2 in size, there is a very complex lan and wlan nbn enabled tree network that has a server room and cables running throughout. There are 5 wireless routers and the current speakers a visible in spotify via at least 2 different wifi routers. I am looking to transfer the sound system ownership of the new house and merge it with my current (small in comparison) s2 sonos wireless speaker network. The pre-existing speakers are built into the ceiling and are indoor and out door (there are around 15 speakers in 3 rooms).  I think the old system is about 5-10 years old and the mounted installed sonos s1 wired speakers might have integrated amps and the system seems to be run via lan network, with inputs via the wifi routers coordinated via a netgear switch in the server room. There is no access to the roof above the speakers and i can not see and independent control hub or amp.

What speakers and devices can you see on the network? And in the app? And physically?

I would first check app compatibility found here:

https://support.sonos.com/en-us/article/sonos-app-version-compatibility
 

Some of the older speakers may not be compatible with the S2 app and would either need to stay on that app version or be removed from the network.

The ceiling speakers should all be powered by Amps, that may be located inside the server room. Again refer to the compatibility list to find out if the Amps are able to be updated.

Since Sonos is controlled by the app, you won’t find any volume knobs around the house, but you can use an old tablet as a main controller for the system.

Post some pictures of the server room and rack so that we can offer more guidance.
