A quick demo migrationYou have two options for migration:

1. Quick and simple using our online utility2. Highly configurable using our desktop utility

www.ldcvia.com

I’ve migrated my data, now what?

You have three options for accessing your data:1. Use our pre-built templates for Document Libraries,

Discussions, Teamrooms or archived Mail files2. Use LDC Via Lens to configure a simple application

template with no coding required3. Build your own application using our API

www.ldcvia.com

What development platform?

The answer is simple: whatever platform you preferIn this session we’re going to show the creation of the same, very simple application, using React, a client side JavaScript library, node.js, a server side JavaScript framework, and Vaadin, a modern Java development framework.

www.ldcvia.com

What’s the application?We only have about 10 minutes per language, so it’s going to be a simple person directory. It will show the list of people in the database and allow the creation and editing of documents that have been migrated from Notes.
