Database problem after upgrading from 4.3 to 4.7

I'm getting the following error in my log:

2020-01-20 21:23:31  INFO: HikariPool-1 - Starting...
2020-01-20 21:23:34 ERROR: HikariPool-1 - Exception during pool initialization. - Unsupported type 17 [1.4.200/3] - IllegalStateException (... < DataManager:139 < *:89 < Context:292 < Main:110 < ...)

How do I fix this?

Nevermind, I fixed it by upgrading to 4.4 first and then up to 4.7.
