On the one hand, an upgrade is cheaper. On the other hand, some reporters prefer to still have access to their legacy CD-ROM because they operate in a working environment that:

• has no Internet access, but access from a smartphone or tablet is necessary for research/job prep
• has Internet access, but the connection is weak or otherwise unreliable
• differs by depo/job location

In such cases it is desirable to retain the Version 4 CD-ROM legacy software for situations where Internet access is unavailable and use the web-based programs when reliable access is assured.

Prospective upgraders are encouraged to decide whether access to Version 4 support is of sufficient importance to warrant purchase of a web-based product at the full price or upgrade price before placing an order, bearing in mind that Supplementary Brief Packs are not compatible with the Version 4 legacy programs.
