The Overview section displays the migration complexity at a glance. It concentrates essential complexity measures for the source to target migration.
The Overview section contains 3 areas:
Overall Migration Complexity gauge
Findings per Impact Level counters
The migration complexity level for any given source is calculated relative to a specified target. To initiate the analysis process and display information in the Overall Migration Complexity, Findings per Impact Level, and Summary areas, select a target.
Overall Migration Complexity
The Overall Migration Complexity gauge shows the result of the analysis. The gauge is divided into 3 segments, denoting the low, medium, or high complexity level.
With no target selected, the gauge is desaturated and does not indicate a migration complexity score.
Findings per Impact Level
This section focuses on the feature findings and their quantities. Three swatches represent migration complexity levels. The counter shown on each swatch represents the number of features detected in the source and taken into account when computing the complexity score.
The score calculation considers several factors besides the number of features per each complexity level. The gauge may show an overall complexity that does not map directly to the high category's relative or absolute features count.
With no target selected, the findings counters are not shown. To display the counters, select a target.
The Summary area provides an executive-summary style text describing the analysis result. It highlights the overall score computed and the source to which it applies. The summary also mentions any exclusions or licensing settings that may have caused the calculation to skip or ignore certain features. These include:
Exclusion of all features associated with a particular schema exclusion
Exclusion of certain features excluded under feature exclusion
Exclusion of certain features or number of features due to licensing limits
For more details about the feature and schema exclusions, see Sources.
With no target selected, the Summary area does not provide information about the migration complexity and shows the following message:
