Welcome to the PMC community. I hope your stay here is good so far. If you need any help with things, let me or anyone of the PMC staff know. We're a friendly enough bunch.
Now this is a rough mapping and you should use the version dropdown box to choose the version that's right for you.
But I see that things did move around from update to update. Like you said. But again that depends weather or not you used the Bedrock Edition or the Java Edition. Also bookmark the seed map here...
I was looking into this seed and I'm surprised how easy it is to set up in a server situation. Not only that, I gave it a shot in my private test server with other words and such. Suffice it to say, you got a good seed. lol
