Raise temples one block up in Minecraft 1. 14?

I've built a temple in my singleplayer world and have noticed late that he has a block higher.

I had been looking for solutions to move in Vanilla 1.14 this temple by one block, have synonymous found something, but do not understand the explanation with the / clone Command in the Command block

You can look at a tutorial to understand the clone command.

Or you install a Bukkit server with WorldEdit. But also there you have to look at a tutorial to understand Bukkit and WorldEdit.

All of these commands also work in 1.14

The problem is that I have exceeded the maximum block number

Then part of your building in different areas.

How big is he?

Apparently more than 32000 blocks, that's the limit for / clone.

Then divide the building on…
