Prior to SharePoint becoming a usable document management solution, Open Text Livelink was an excellent solution being highly configurable and customisable. Indeed prior to 2007 Deltascheme implemented many Livelink systems including some complex integrations.
When it comes to a migration from Livelink to Office365 there are the three usual aspects to consider:- content, integrations and customisations. Most aspects can be re-engineered in SharePoint online although there are some features of Livelink that do not have a like for like feature in SharePoint such as the ability to capture a generation in Livelink. As for any migration, a proven methodology that starts with a detailed content audit is the key to successfully migrating off Livelink.
