The cPanel Transfer Tool is incredibly powerful, but at times and given the wrong servers/bandwidth, it might hang.
Use top to look for rsync processes. In the beginning you’ll see a lot, and later you’ll see nothing.
To troubleshoot the issue use the command line:
Start with this grep:
ps awuxff | grep trans
Next, pick the hung parent process and grep it:
ps awuxff | grep examplecocopya20250609153359bagY root 2302770 0.0 0.1 283272 35100 ? S Jun09 0:26 transfer_session - examplecocopya20250609153359bagY - MASTER root 2302788 0.0 0.5 494144 188848 ? Sl Jun09 0:05 \_ transfer_session - examplecocopya20250609153359bagY - RESTORE:2 root 2302789 0.0 0.5 489724 184984 ?

Sl Jun09 0:08 \_ transfer_session - examplecocopya20250609153359bagY - RESTORE:4 ...
You’ll see a bunch of hung processes attached to a parent. Next, start strace the processes one by one. Yes, you heard that right, the whole lot. Some numbers are sequential so you’ll be okay:
timeout 2m strace -p 2502332 ... timeout 2m strace -p 2302770
You’ll probably find this kind of crap:
newfstatat(AT_FDCWD, "/var/cpanel/transfer_sessions/examplecocopycopya20250609153359bagY/.abort", 0x14844732cec0, 0) = -1 ENOENT (No such file or directory) newfstatat(AT_FDCWD, "/var/cpanel/transfer_sessions/examplecocopycopya20250609153359bagY/.pause", 0x14844732cec0, 0) = -1 ENOENT (No such file or directory) wait4(-1, 0x7fff7b5ed0e4, WNOHANG, NULL) = 0
Next, I suggest you actually get cPanel to look at is. They have brilliant engineers. They might bombard you with backup and restore boilerplate but perhaps check -maybe the transfers actually worked.
