Re: WinSCP Key-Based Auth Issue in Parallel Migration (2012 → 2022 Server)
Yes, in general you can use the same key pair. The problem is likely elsewhere.
Please attach a full session log file showing the problem (preferably logs from both machines).
Please attach a full session log file showing the problem (preferably logs from both machines).
To generate the session log file, use
/log=C:\path\to\winscp.log command-line argument. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.
