Hello.
YES You can make this System Copy from Non-Uc to Non-Uc.
The New SWPM only accept unicode systems for new installations (no for system copy).
When you made an system copy with swpm, in target system you can select unicode or non unicode system/kernel depend of codepage of your export file (non-unicode in your case)
I have your same system and I made this migration recently.
Hope that help.
Regards.!
