How to update oxide without map wipe?
I am new to the rust modding and server hosting community, and have started a modded server, with custom world size settings. 

When I reinstalled oxide for the updated rust, then porter over all the server.cfg’s and plugin configs, the map was reset. 

How is can I prevent a map reset? Is there a more seamless way to auto update oxide with just a server restart, and no reset? 

Thanks 
Oxide is unrelated to your server settings and map save. Rust and it’s configuration is the o my thing related to Rust map saves, so if it wiped, it was from either a Rust update or your configuration of Rust.
You can try to save all entities by any plugin (public or custom) and if map mesh was changed simply -> return them back (by plugin too)
No, not after a full map wipe.

Once a month Facepunch changes the map protocol which also slightly changes the map generation seed.  With a different seed, that means a different map.

For that reason, the first Thursday of every month is a "full map wipe."  You cannot save entities on the world map, because even if you did, they wouldn't be in the same place they were before.  The map entities would be inside the world, or floating in the sky.

At bare minimum, you must wipe at least once per month until Facepunch changes this policy.
It is possible but not easy and requires more work than most people would want to do

Thanks for the info, I was unaware of the forcewipe every new month's thursday. 

I apprecieate your help.
