Hi All,

I am new to ELK and we are moving our indices from ELK7 to ELK8. However, i am getting error while reindexing the existing indices

Welcome!

It might be because you did not set the same mapping for both indices.

It seems indices are having different type of mapping:

Indices example 1:  
"syst-jira-apdex-2023-03" : {  
"mappings" : {  
"properties" : {  
"@timestamp" : {  
"type" : "date"  
},  
"agent" : {  
"properties" : {  
"ephemeral\_id" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256

Indices example 2:  
syst-confluence-access-2023-05-29" : {  
"mappings" : {  
"properties" : {  
"@timestamp" : {  
"type" : "date"  
},  
"agent" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},
