I have killed the Ender dragon in my survival world in 1.8, so the End island was also generated in 1.8.
I have been searching for the teleporter that teleports you to one of the islands around the main island. It spawns after defeating the Ender dragon, but I did not find it. This is probably caused because killing the Ender dragon in Minecraft 1.8 did not trigger the teleporter.
Is it possible to find an End city after updating Minecraft from 1.8 to 1.9?

I think that the best solution is just to remove old map of the END and let it generate again - by new methods of generation and also with new dragon and cities.
The thing is that even main island is generated in new behaviour, which may be the problem why even after another kill of dragon you won't find any portal or so. (It may be just bugged inside of blocks or so, or it may not even be there)
You can do it by deleting region files from your save, but be sure you are NOT in that dimension and that you will lose all buildings in the end. For being sure, make a backup.
