I have upgraded elastic 6.8 to 7.17.
and i have taken the .security-6 file backup as .security-6-reindexed.
but. while performing upgrade to 8.x.x version. nodes are showing the following error
java.lang.IllegalStateException: Alias [.security] points to more than one index: [[.security-6/cOoc42eJRo2xwdocrrgEeQ], [.security-6-reindexed/kC-abcdefghi]]
and elastic user is not able to authenticate. any suggestion, how can i fix this.
