The vault tool from Coinbase no longer works:
https://bitcointalk.org/index.php?topic=5316286.0
But if you read to the bottom: https://bitcointalk.org/index.php?topic=5316286.msg62141240#msg62141240
Someone did make a working version at least as of 6 moths ago or so.
I can't comment on the safety of it or if it still works but it did back then.
Once you run the tool if it does work move your coins ASAP.

Hello Dave!!
Thank you very much for your reply, I saw this but I have no idea how its working...
The usage is 1:1 same as with the old tool. For complete instructions, visit https://github.com/coinbase/multisig-tool/blob/master/README.md
In short:
download & run the project with npm install and make run (also you will need python3 to be able to run local server)
input your xpubs in step 1, then (optionally) go offline and input the rest for step 2. NOTE: For destination address, use P2SH address (starting with "3"). Native SegWit (bech32) addresses (starting with bc1) reportedly do not work.
raw transaction will be generated. It will send 100% of your funds (minus the fee) to the destination address. You can use https://coinb.in/#verify to verify that it's looking good, mainly if the destination address is matching.
broadcast raw transaction using any bitcoin client (for example, run broadcast("....") in Electrum console)
you are done!
what is npm install? python3
? run local server I dont understand??? where is the link to download the project? I'm not very good with computers and internet so all this information its new for me 
Thanks again, maybe we found a solution for me !!!!!!
