Re-ripped content and uploading higher rate version

Question

I have been re-doing albums which haven't been matched and which have been ripped originally at 128kbps. I have re-ripped at a higher bit rate. How do I tell whether itunes has done what it should have done and uploaded the replaced tracks with the higher bit rate version? Some of the re-ripped tracks also matched when they hadn't before. Additional cds added after itunes match enabled do get ripped then matched or uploaded at the higher rate. The 'run itunes match' doesn't seem to make it change anything.
The match system has mostly been painless apart from one matched track failing to download of 3500 matched ones. How do I report a failed download or is it done automatically?
There isn't a view option to see icloud bit rate to distinguish between versions.
Is the easiest way to delete the re-ripped album with 'delete from cloud' and then drag it back in from the trash if it hasn't uploaded the better version automatically?

Answer 1

Ok, so to ensure that you have the higher quality Song uploaded:
1.  Copy your higher quality Songs from iTunes to local folder;
2.  Delete Songs in iTunes, including 'delete in iCloud' option;
3.  Allow 6-12 hours for iTunes Match servers to synchronise (ensuring original really has gone from iCloud);
4.  Turn iTunes Match off;
5.  Import Songs from folder;
6.  Turn iTunes Match on - allow it to complete the 3-step process.
