Hi,

I'm trying to reindex my data using the \_reindex feature.

Prior to this I wan't to create the daily indices with new mappings.

How can I automatically extract the current daily name, add \_v2 to the name and add a new mapping for each of the indices?

One of the old indices and mapping:  
{  
"sipdump-2018-04-30": {  
"aliases": {},  
"mappings": {  
"Info": {  
"properties": {  
"from\_server": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword",  
"ignore\_above": 256  
}  
}  
}  
}  
}  
}  
}  
}

What I'm trying to accomplish:  
{  
"sipdump\_v2-2018-04-30": {  
"aliases": {},  
"mappings": {  
"Info": {  
"properties": {  
"from\_server": {  
"type": "ip"  
}  
}  
}  
}  
}  
}
