+ * 1) Deserialize all stored [`ChannelMonitor`]s.
+ * 2) Deserialize the [`ChannelManager`] by filling in this struct and calling:
+ * `<(BlockHash, ChannelManager)>::read(reader, args)`
+ * This may result in closing some channels if the [`ChannelMonitor`] is newer than the stored
+ * [`ChannelManager`] state to ensure no loss of funds. Thus, transactions may be broadcasted.
+ * 3) If you are not fetching full blocks, register all relevant [`ChannelMonitor`] outpoints the
+ * same way you would handle a [`chain::Filter`] call using
+ * [`ChannelMonitor::get_outputs_to_watch`] and [`ChannelMonitor::get_funding_txo`].
+ * 4) Reconnect blocks on your [`ChannelMonitor`]s.
+ * 5) Disconnect/connect blocks on the [`ChannelManager`].
+ * 6) Re-persist the [`ChannelMonitor`]s to ensure the latest state is on disk.
+ * Note that if you're using a [`ChainMonitor`] for your [`chain::Watch`] implementation, you
+ * will likely accomplish this as a side-effect of calling [`chain::Watch::watch_channel`] in
+ * the next step.
+ * 7) Move the [`ChannelMonitor`]s into your local [`chain::Watch`]. If you're using a
+ * [`ChainMonitor`], this is done by calling [`chain::Watch::watch_channel`].
+ *
+ * Note that the ordering of #4-7 is not of importance, however all four must occur before you
+ * call any other methods on the newly-deserialized [`ChannelManager`].
+ *
+ * Note that because some channels may be closed during deserialization, it is critical that you
+ * always deserialize only the latest version of a ChannelManager and ChannelMonitors available to
+ * you. If you deserialize an old ChannelManager (during which force-closure transactions may be
+ * broadcast), and then later deserialize a newer version of the same ChannelManager (which will
+ * not force-close the same channels but consider them live), you may end up revoking a state for
