How to upgrade the underlying bitcoind?

[phuongnd08]

My current bitcore-node is running on top of bitcoind 0.12. I would like to upgrade to 0.15. How can I do it?

I'm also interested in doing this for bitcoind and other altcoin implementations.

I've been looking at doing this as well. At this point in my research, I think the limiting factor is whether or not the underlying bitcoind daemon supports extra indices (such as the address index) needed for the insight-api. Bitpay appears to maintain a fork supporting this at https://github.com/bitpay/bitcoin, but the latest stable tag is at 0.13 of core's version

Can someone (ideally a bitpay member) confirm this is the case?

The underlying submodule ‘bitcoin’ is no longer maintained because two developers are no longer working at bitpay.

And satoshilabs tried to maintain the project. Btc veriosn is Here, which support V0.15 and Bch version is Here.

I have not tried these submodule yet, if they work fine, please tell me.
