Ask comrades for help.

My computer is a mac system. After upgrading from 1.8.1 to 1.11.2, the old archive cannot be opened. But I can create a new archive.

Does anyone know what's going on?

The old archive records my entire youth, I can’t bear to lose it

I currently have a backup of version 1.7.1

向同志们求助。我的电脑是mac系统，从1.8.1升级到1.11以后老存档就打不开了。
但是我却可以创建新存档。
请问有没有人知道这是怎么回事啊？

Do you still have the original save file, which you haven't tried to open in 1.11.2? Try opening that in KSP 1.8.1 and if it doesn't load, your save is probably corrupted.

Go into KSP/saves/your save/backups, grab the most recent backup file and copy+paste it into KSP/saves/your save; rename the current persistent.sfs save file something else (e.g. persistent1.sfs), then rename your backup file persistent.sfs; this will make KSP open the backup file when you try to load the save.

If that loads correctly you'll have your save game back, though you'll likely lose a little bit of progress from after the point where the backup was made; if it still doesn't load, it might be your KSP 1.11.2 is corrupted in some way- first, copy your save files somewhere outside of the KSP folder tree, then uninstall and reinstall KSP completely, then add your saves back in and try to load them.
