Convert WebStorage to C3

I have a game created with C2 that uses WebStorage, can I convert that data to C3 so that my players can use the WebStorage data?

Thank

The WebStorage plugin in C2 was deprecated 5 years ago and hasn't been supported since then.

If I port it to C3 all users will lose their saved games.

Local Storage can read Webstorage data?

Couldn't I do it in C3?

Back in 2015 when WebStorage was originally replaced with Local Storage in Construct 2, it was noted that they aren't compatible:

Also note that since Local Storage uses a different storage mechanism, it will not be able to read any existing data saved with WebStorage.

WebStorage uses a different storage backend behind-the-scenes - one which is slower, has a very low capacity, and loses data types. Local Storage is faster, has much higher capabity, and preserves data types. You sure left it a long time to upgrade!

I didn't want my players to lose the game ...

I guess the only solution is to release another version in C2, which will load all Webstorage keys and re-save them with Local Storage.

Then wait a few days/weeks and publish a proper C3 update. Some players may still lose their data (those who skipped that C2 version), but most players should be ok.

That may be a solution, I could leave the version for 15 days and then upgrade to C3.

Thank you.
