Neter reset after migration to sparkedhost

I migrated my world folder to sparkedhost but upon entering the nether, it appears completely reset.

I doublechecked the DIM folders and all the files are there.

The console outputs errors like these:

[18:56:49] [Server thread/ERROR]: Chunk file at [-1, -2] is missing level data, skipping

[18:56:49] [Server thread/ERROR]: Chunk file at [-2, -1] is missing level data, skipping

[18:56:49] [Server thread/ERROR]: Chunk file at [-1, 0] is missing level data, skipping

[18:56:49] [Server thread/ERROR]: Chunk file at [-3, -10] is missing level data, skipping

[18:56:49] [Server thread/ERROR]: Chunk file at [0, -10] is missing level data, skipping

[18:56:49] [Server thread/ERROR]: Chunk file at [6, -10] is missing level data, skipping

Does anyone know why this is happening and if there's a fix available?

Thanks

Quote from Joshua

To be fairly honest, if you are running your server on another host, you should be asking support there as well.

I am asking there as well, haven't heard back yet but I was wondering if theres anything the community here knows. from also migrating their own worlds over.
