Combining two DHCP Servers, same scope

I  have two DHCP Servers on a /16 network. Running 2016. Both have the same scope, but different ranges of exclusions. Example:

DHCP1 - Scope 1 10.10.0.0
10.10.0.0 - 10.10.10.255 For Distribution
10.10.0.0 - 10.10.3.255 excluded
10.10.5.1 - 10.10.7.255 excluded

DHCP2 - Scope 1 10.10.0.0
10.10.0.0 - 10.10.10.255 for Distribution
10.10.4.1 - 10.10.4.255 excluded
10.10.8.1 - 10.10.10.255 excluded

So if you do the mental math there... it's quite messy. As a side note, in the actual environment there is about 30 different exclusions. As far as I can tell, they don't overlap... but it is quite confusing. I want to fix this!

What would be the best way to combine these two DHCP Servers in to one? I want to turn DHCP1 in to my primary, with DHCP2 in to a hot standby. But I want to try my best to not lose the reservations/leases already given out on DHCP2...

I tried a export/import, seeing if I could possibly just edit the export and combine both exports in to one, but it doesn't look like it is plain text.

Any ideas?
