I have two vcsa in linked mode. The partnership/replication was all good when they were under 6.7. After upgrading one of the nodes to 7.0, the partnership is broken, looks it no longer has a valid agreement in between the upgraded node (7.0) and the not-yet-upgraded node (6.7). And when I try to upgrade the another node to 7.0, it complains "VMDir Replication between partners is not working" then stops, when I did a showpartners cmdlet, they can still see each other but the status available is at "No":

Partner: abcde.ca
Host Available: Yes
Status available: No

What should I do at this point? Thanks.
