The upgrade strategies you choose directly affect how long an upgrade takes to complete, the effect an upgrade has on your network, and the fundamental structure of your site hierarchy.
Upgrade strategies are divided into two major categories:
- In-place upgrades
- Side-by-side upgrades
You are not limited to a single upgrade strategy for the entire site hierarchy. Because of the complex nature of Configuration Manager 2007, you might decide to employ a mixture of upgrade strategies that best fit your needs.
In-place upgrades offer the following benefits:
- Generally easier to do and require less
planning than side-by-side upgrades.
- Better suited for use when you do not want to
modify any computer hardware currently in use in your Microsoft
Systems Management Server (SMS) 2003 sites.
- Do not require the purchase of new
- Do not require site boundary changes between
- Do not require clients to be reassigned to
Side-by-side upgrades offer the following benefits:
- Better suited to upgrade sites when new
hardware will be used.
- Easier to revise the existing SMS 2003
- Allow you to rearrange sites and clients
within the site hierarchy.
