Ready when you are.
ABOUT THIS TOOL

Merge carefully and test before a site migration.

Up to 1,000 mappings. Sources use exact, case-sensitive paths without query strings or fragments. Targets may be absolute HTTP/HTTPS URLs or paths on the source site. Encoded slashes and backslashes are rejected. Chains can be flattened; loops and conflicting destinations block export. The bundle contains a rules snippet to merge into your existing IIS URL Rewrite configuration, not a replacement web.config. Existing rules and server settings still need testing.
