History missing after renaming a folder

SVN Mirror
#1

There is need to migrate one folder from SVN parent repository. But history is not coming properly.
Parent SVN Repo path: https://svn.dts.fm.rbsgrp.net/grouptreasury/ (Attached is the screenshot - SVNParentRepo)
The folder https://svn.dts.fm.rbsgrp.net/grouptreasury/LewtanMortgages/ were previously https://svn.dts.fm.rbsgrp.net/grouptreasury/Lewtan Mortgages/ and was renamed.
After this, the folder https://svn.dts.fm.rbsgrp.net/grouptreasury/LewtanMortgages/Trunk/ was renamed to https://svn.dts.fm.rbsgrp.net/grouptreasury/LewtanMortgages/trunk/
Now, when we are migrating https://svn.dts.fm.rbsgrp.net/grouptreasury/LewtanMortgages/ , complete history is not coming and the history comes only from the day the folders were renamed.

Requirement is to move: https://svn.dts.fm.rbsgrp.net/grouptreasury/LewtanMortgages/ (Screenshot attached)

We have used below mapping
Subversion Project URL- https://svn.dts.fm.rbsgrp.net/grouptreasury/

trunk = LewtanMortgages/trunk:refs/heads/master
branches = LewtanMortgages/branch/*:refs/heads/*
branches = LewtanMortgages/Releases/*:refs/heads/Releases/*
tags = LewtanMortgages/tag/*:refs/tags/*
shelves = LewtanMortgages/shelves/*:refs/shelves/*

Hello.

If those directories were renamed using SVN facilities for renaming, then adding old paths to the mapping configuration should resolve the problem. For this case, try to use the following mapping scheme:

trunk = LewtanMortgages/trunk:refs/heads/master
branches = Lewtan Mortgages/Trunk:refs/heads/oldtrunk1
branches = LewtanMortgages/Trunk:refs/heads/oldtrunk2
branches = LewtanMortgages/branch/*:refs/heads/*
branches = LewtanMortgages/Releases/*:refs/heads/Releases/*
tags = LewtanMortgages/tag/*:refs/tags/*
shelves = LewtanMortgages/shelves/*:refs/shelves/*

If the directories were renamed by SVN command but by using OS commands or equivalent way, then it may be not possible to get the whole history as the add-on may not be able to trace the parents and thus history.

Thanks for the suggestion. We were able to get most of the history except for a month or two and that might be because of the reason already mentioned.
