Issue with time machine backup
I took MacBook Pro backup from my old MacBook 2013 non-encrypted (High Sierra) in my Toshiba HDD as time machine and sold my MacBook. Now I can not transfer files to my new Macbook. While setting new Mac with time machine, it is showing fresh copy of OS only. May be new mac2019 (Mojave) can not read from time machine backup. In my time machine, I can not copy backups.backupdb folder manually too and getting message 'the volume is the wrong format for backup'. Time machine is already Mac OS extended (journaled) format. I can copy other folders from time machine which I have added by copy paste. I have tried cloner software, but it is not working. Is there any way to restore my data?
