Breaking svnsync mirrors

We're in the process of migrating & upgrading our Subversion installation. In doing so we're encountering a handful of repos which were impacted by issue 4129 (https://subversion.apache.org/docs/issue4129).
The fix for this (to dump & reload) has been successful with most of the repos, however to do this you need to have sufficient storage to duplicate the repos; and one of the repos in question is over 700GB in size!
As an alternative, I'm looking to use svnsync to fix this repository; I'm just looking to clarify the process for completing this.
On new host:
Allow the data to copy across ... then ...
At this point there will be a copy of the existing repository. Periodically we'll then be able to run the 'svnsync sync' and 'svnsync copy-revprops' to copy across any new revisions.
We'll then schedule the cutover weekend so would perform something like:
1) Disable access to repos on old host.
I just want to confirm that my process seems sensible and that what I've described regarding breaking the svnsync mirror is correct.
If anyone can see anything that I might have wrong or missed?
