I dunno
In WWII we had a load of WWI era destoryers bought of the us that saw service as we were short of ships.
I see no reason why back water and outer rim systems are using capital ships that are like 50 or 60 years old or older.
Wasnt a WWII battleship used for firesupport in desert storm?
You dont just stop using old kit because someone makes something better, you move it down a 'defence level' or to a less strategic area or you sell it to less advanced nations (or even races in SW)
