Update Datafile

There is no datafile changes from LiteDB v3 to v4. You can use same database file!

To upgrade your datafile from LiteDB v2 you can use "upgrade=true" in connection string. Like this:

var db = new LiteDatabase("filename=old.db;upgrade=true");

LiteDB will update (if is necessary) to new datafile format. You can use shell too:

> upgrade my-old-file.db

if your old datafile is password protected, use:

> upgrade filename=my-old-file.db;password=mypass

Only v2 datafile is supported (file format 6).
