Opposite. P4 labels are not exported to Plastic.

Thanks, it worked. But the labels did not sync, and there were also many empty folders that were once deleted.

The server 'unitsys@cloud' requires encryption, but your server is not configured with the encryption key. To configure your local server make sure you become the admin of the server (owner), try again and you will be asked to enter encryption key. Otherwise, ask your sysadmin or search 'Encrypt all data' in the online docu.

I got this error, but I couldn't find the encryption key. When creating the repository, I put the encryption checkbox, but I didn't do anything else.
My command: 

cm sync SeverskMuseum@<REP>@cloud p4multibranch perforce:1666 --mainbranch=//SeverskMuseum --branchesfolder=//SeverskMuseum --user=<USER> --pwd=<PWD> --tmpwkpath = c:\p4wks

p.s this repo have only main branch

An error occurs during synchronization. Initially, the file with the cyrillic was not found (it was a first submit). I called p4 obliterate and started syncing again. The error remained the same but with a new file that was in the second commit. I am assuming it does not find all files.
 

C:\WINDOWS\system32>cm synchronize br:/main@SeverskMuseum@SERVER@cloud p4 perforce:1666 //SeverskMuseum --user=USER --pwd=PASSWORD
