Description

While migrating from angular material 19 to 20, on cli there is a message that says -

"UPDATE some/dummy/file/path1 (869 bytes)
UPDATE some/dummy/file/path2 (7981 bytes)
UPDATE some/dummy/file/path2018 (7981 bytes)
UPDATE some/dummy/file/path2019 (194 bytes)

Migration completed (2109 files modified)."

But on my git I can only see 25 file that have been modified from the script. Is this a bug? Or what is being updated?
