Transform the world (main -> additional)

Sponge Sponge Support
1

I have the main world and additions world.

..server\world
..server\world\world2

I created another main world “world1”

..server\world1

Added an additional world

..server\world1\world2

How do I add an existing main world (the last)?

..server\world1\world

I tried to assemble a structure:

advancements
data
playerdata
region
stats
forcedchunks.dat
level.dat
level.dat_old
level_sponge.dat
level_sponge.dat_old
session.lock

into the directory world
but the sponge does not detect this world

Is this even possible?

I decided. You need to change the Dimension ID in level_sponge.dat.

World: DIM-1
Dimension ID: -1

World: DIM1
Dimension ID: 1

World: world1 <- primary (..server\world1)
Dimension ID: 0

World: world <- secondary (..server\world1\world old primary)
Dimension ID: 2 <- not busy

Structure:

data
playerdata
region
forcedchunks.dat
level.dat
level_sponge.dat
session.lock
