Samba versions in ports and updating to newer version

Hi=20
I am currently using samba419 from packages but when I ran pkg upgrade I =
got a message I should go to a newer version.
If I run pkg search I get the following versions, all with the same =
description:

$ pkg search samba4
samba416-4.16.11_12            Free SMB/CIFS and AD/DC server and client =
for Unix
samba419-4.19.9_13             Free SMB/CIFS and AD/DC server and client =
for Unix
samba420-4.20.8_2              Free SMB/CIFS and AD/DC server and client =
for Unix
samba422-4.22.10_1             Free SMB/CIFS and AD/DC server and client =
for Unix
samba423-4.23.8_1              Free SMB/CIFS and AD/DC server and client =
for Unix

In /usr/ports/UPDATING I see no relevant remarks about samba.
Can I just do pkg remove samba419 followed by pkg install samba423 ?
Or are there issues to expect ? And where can I find documentation of =
those issues ?

Cheers,
