Cube Processing approach when Process only the Current Partition?

Question

Could you validate my SSAS Processing strategy for the given scenarios:<o:p></o:p>
Background about cube and data:<o:p></o:p>
A Sales cube has Partitions for each year for "Sales" Measure Group and it associated with dimensions "Product" and "Sales
Rep". Both are type 1 Dimensions.<o:p></o:p>
Here some time user will re-classify the products, product Hierarchy(Product -> Sub Category - > Category);  <o:p></o:p>
Similarly re-classify Sales Rep (Sales Rep –> District Manager -> Regional Manager)<o:p></o:p>
Processing strategy:<o:p></o:p>
1. Process(full process) only the current Partition every day.<o:p></o:p>
2. Perform "Process update” for all the dimensions. (going for process update, as Dimension full process is processing all the old partitions
of measure groups)<o:p></o:p>
Questions:<o:p></o:p>
1.   
What are disadvantages when processing only the current partition? <o:p></o:p>
2.   
Does the old partitions data will roll up as per the hierarchy changes, when I go for Dimension “process update” options.<o:p></o:p>
 Thanks,

The strategy looks good. Partitioning is the way to go to reduce processing time. However, keep in mind that partitions are only supported in the enterprise version.
1. Other than not being able to refresh older data from other partitions, i don't see a downside in processing the most recent partitions. 
2. Yes. A process update should touch all the dependent partitions.
