Its still possible for JIRA Agile's upgrade tasks to create duplicated LexoRank fields, and this is causing re-indexing to fail with the following errors:

It is currently unknown how JIRA Agile is creating these duplicated rank fields. You can easily identify this by navigating to Administration >> Issues >> Custom Fields, check if there are multiple Rank custom fields of type Global Rank. (Not obsolete)
When you have multiple rank fields, JIRA may be using the wrong Rank field while indexing issues. (The rank field that was not used in the balancing) So while indexing JIRA fails to find the maximum marker and minimum row.
A KB has been created describing this in detail: https://confluence.atlassian.com/display/AGILEKB/Cannot+reindex+jira+due+to+Expected+exactly+2+rows+the+maximum+marker+row+and+the+lowest+ranked+row+for+rank+field
