i apologize if this is 1242032nd thread to this particular upgrade topic.
After getting rid of the different mapping-types of fields in different ES-types, i now got the "problem" to have some fields with dots in it in almost every index, mostly completely nonsense fields that got produced by an not 100% working Logstashfilter.
Migration-Tool is telling me after the last Update that it is a big issue, however a long time it displayed the "dot-fields" as a yellow error - meaning it is not optimal and those fields wont continue to work in ES2.0.
When i upgrade my ES 1.7 to 2.1 or 2.3, will the upgrade process fails cause of this annoying fields or will there be a warning displayed?
If it fails, why? Seems like ES 2.0 can deal with dot fields, as it does e.g. with the ".raw" multi fields.
It would be a work of months to reindex all of the indices, so i hope i could get around it
Thanks for your response.
