Sure.

I'm assuming Windows, but if it's linux the procedure is the same, except the file is /home/username/.litecoincash

Anyway

Make sure the client is not running. (LitecoinCash core).
Navigate to C:\users\username\appdata\roaming\litcoincash

Delete everything but wallet.dat

Copy bootstrap.dat to this folder

Launche LitecoinCash core

Get a stiff drink and wait.


While you wait, if you want, you can import your private keys.

Go to file, import private key, and paste it in. Don't choose rescan until you've entered every key, then choose rescan. This WILL slow indexing by the amount of blocks already scanned. Given where the fork is, you can get away without the rescan, as it's indexing anyway.

I just did this, it works fine
