Problem while upgradeing elastic from 1.4 to 7.0

Hello,

I have an index mapping that has  dynamic_templates  that use groovy but I found that it is not supported in new Elasticsearch versions 

"dynamic_templates":[ { "categories_value":{ "match":"category_value_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } }, { "negative_keyword":{ "match":"negative_keyword_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } }, { "also_serving_area":{ "match":"also_serving_area_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } }, { "also_serving_city":{ "match":"also_serving_city_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } }, { "also_serving_directory":{ "match":"also_serving_directory_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } }, { "company_occasions":{ "match":"occasion_id_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } }, { "company_occasions_categories":{ "match":"occasion_category_*", "match_mapping_type":"string", "mapping":{ "type":"integer" } } } ]

so is there any other replacement to the groovy that I can Use in elasticSearch ?

Thanks
