Haven’t used LS before? But can you try using their API to export customers and reimport into stripe? What you will not be able to do is import their card data. I don’t think any payment provider can do that easily. That is likely a compliance no no.
Also, if you also need your customers transaction data, that won’t happen, because you can’t just migrate that between providers.
