Hello,

**Here is the list of changes/recommendations (I hope I don't miss anything):**

1. Logstash:  
ES output plugin will change the document\_type from logs to doc

2. ElasticSearch:  
Indices created in Elasticsearch 6.0.0 or later may only contain a single mapping type.  
_default_ mapping will be removed on ES 7 (so it's better to not use this one).

3. Concerning the upgrade:  
Recommended upgrade order is Elasticsearch --\> Kibana --\> Logstash

**Actual infrastructure:**

1. Logstash 5.6 is inserting data to Elasticsearch 5.3 and Kibana 5.6 is used to view the data.

2. Logstash is creating different indexes every days with `index => "logstash-index1-%{+YYYY.MM.dd}"` (using custom templates stored in Elasticsearch) in Elasticsearch.

3. For the predefined templates I use the following mapping:  
`... "mappings" : { "Log" : { "dynamic" : false, "_source" : { "enabled" : true }, "properties":{ ....`

**Upgrade to ELK 6**  
I plan to update ELK stack to 6.x (with the shortest downtime possible), and I've few questions about how to do it:

1. Before starting the upgrade can I update the mapping of the templates to:  
`... "mappings" : { "doc" : { "dynamic" : false, "_source" : { "enabled" : true }, "properties":{ ...`

Then do I need to add the document\_type value and set it to doc?  
And few days later I will update the ELK stack in the recommended order.  
Can it work in that way?

1. If I upgrade ES and Kibana first, can I let Logstash in the 5.6 or will I have issues when the new indexes will be created the day after?

2. Or must I stop Logstash before the daily indexes creation, and then:  
a/ Upgrade the ES templates as mentioned previously.  
b/ Upgrade ES --\> Kibana --\> Logstash  
c/ Start ES --\> Kibana --\> Logstash

Thanks.
