Can I upgrade from 2.0?

[scottberg]

I thought about using Sugar's export in 2.0 and the import into 4.5, but some objects are not supported (eg tasks, meetings, calls, etc).

Any suggestions?

Wow - so this is from an install around the end of 2004 I guess!

I think you only have two options, both less than optimal.

1 - Follow all the upgrades up to the present day (some may not even be on the net any longer, but I'm sure Sugar, or some users, could provide them if asked).

2 - Get someone to do a full data migration for you as a service. Anyone that moves data from Salesforce.com, or other CRMs, into SugarCRM, will have code that can be adapted to migrate your Sugar 2.0 data straight to the latest version.
