What command can i use instead of `ListAccounts`
You can still use the same commands to get a list of accounts and addresses 

getaddressesayaccount: returns a list of every address assigned to a particular account.

listreceivedbyaccount: lists the total number of bitcoins received by each account.


Or as a workaround you can try the trick with the following:

listaddressgroupings: lists groups of addresses that may have had their common ownership made public by common use as inputs in the same transaction or from being used as change from a previous transaction.

listtransactions "*" 1 0 true: List the most recent transaction from all accounts including watch-only addresses.

Hope this helps,

kind regards.
