Moving files from one share on a host to another share on the same host will always be faster when initiated from the host itself, and will always be slow when transferred from the host to a client (and back). Regardless of whether you use Finder, or mv or cp or Carbon Copy Cloner, if the data has to traverse the network, it will be orders of magnitude ...
I'm not exactly sure if this is what you need but you may be able to use either the 'scp' command for remote transfers or the 'cp' command for local transfers.

I will also suggest using Menumeters to measure your network speeds, and use a wired Ethernet connection ...
Is your 'replaced client' the exact same machine name and user as before? if not, you may not have permission to access. The alternative is to take the new client an 'restore from Time Machine' when booted from the recovery partition. This will, of course, wipe the existing data from the hd.

For me the problem was that "Enterprise Connect" had stored the shared drive. Going to Enterprise Connect icon --> Shares and deleting the shared drive solved my issue.
I also searched for the shared drive in the Keychain and deleted the credentials that had been stored.
I have the same issue after updating to macOS Catalina Version 10.15 Beta (19A487m)
I have a network drive connected to a router using SMB:// Its a 8TB readyshare.
This has always connected automatically and is primarily used as a backup. Since the update this has been unavailable and if I try to connect I get the same error as above.
If I try to browse ...
