Actually they are very different products.
Seagate Analysis is a V7 product - based on the version 7 CRPE and was given away as a free product circa 1999. It was a combined ad-hoc reporting, query and OLAP analysis tool - allowing users to model data in client-side "micro-cubes". It could also be used as a traditional OLAP client tool against server-side cubes.
A client/server version was introduced in SI7 and continues to be included in SI7.5, however this version only works by connecting to an "Analysis Server" - where the queries and reports actually execute.
In contrast, Crystal Analysis 8 (currently available in Professional edition only) is a dedicated analytic report writing tool that only works with OLAP data sources. It does not have the ad-hoc query nor the basic report writer that was pert of Seagate Analysis.
Content created with CAP8 (these are .CAR files can be hosted by a Crystal Enterprise server and end users can view and interact with these reports via a web browser.
While it may be considered that CAP8 is in some ways an evolution of SA7 (as both contain OLAP capability) the files created with SA7 are not usable in CAP8 (although they can be used in Crystal Reports 8.5 as they are just RPT files).
I hope this clarifies things...
