如何将整个索引数据从一台 Splunk 服务器迁移到另一台 Splunk 服务器

Question

I have a Splunk server with index data for 650k events. I want to migrate the entire data from one instance to another new instance. I tried using a migration script with data field -27D@d but I can only migrate 50k data. -27D@d is the point from where initial data is available. Can you please help me here? Here's the code:

import splunklib.client as client
import splunklib.results as results
import json
import requests

send_string = ""
service=client.connect(host="host1", port=8089,  username="admin", password="xxxx")
rr = results.ResultsReader(service.jobs.export('search index=my_index latest=-27D@d' ))
for result in rr:
    if isinstance(result, results.Message):
        continue
    elif isinstance(result, dict):
        final = dict(result)
        data = final['_raw']
        send_string = json.dumps({"event" : data,"source" : "test"},ensure_ascii=False).encode('utf8')
    url='http://host2:8088/services/collector'
    authHeader = {'Authorization': 'Splunk 5fbxxxx'}
    #Send data to Splunk
    response = requests.post(url, headers=authHeader, data=send_string, verify=False)
    if response.status_code == 200:
        print("Successfully pushed the data to Splunk source")
    else:
        print("Failed to push the data to Splunk source")

如果host2 上不存在索引my_index，则只需将目录$SPLUNK_DB/my_index 复制到host2，将my_index 添加到index.conf，然后重新启动Splunk。

I managed to do this with the Splunk Docker image. I imagine it's the same with a regular installation.

Note: In this example, $SPLUNK_HOME === /opt/splunk

First I backed it up:

mkdir splunk_backup
cd splunk_backup

# Back up index data
mkdir -p ./opt/splunk/var/lib/splunk
sudo docker cp $container:/opt/splunk/var/lib/splunk/defaultdb ./opt/splunk/var/lib/splunk

# Back up index configurations and dashboards
# - config is at      /opt/splunk/etc/apps/search/local/indexes.conf
# - dashboards are at /opt/splunk/etc/apps/search/local/data/ui/views
mkdir -p ./opt/splunk/etc/apps/search
sudo docker cp $container:/opt/splunk/etc/apps/search/local ./opt/splunk/etc/apps/search

# Back up users and reports
mkdir -p ./opt/splunk/etc
sudo docker cp $container:/opt/splunk/etc/users ./opt/splunk/etc

Then I went to the new server, launched Splunk, and stopped it:

sudo docker run --env SPLUNK_START_ARGS="--accept-license" --env SPLUNK_PASSWORD="FILL_THIS_IN" -p 8000:8000 -p 8088:8088 -p 9997:9997 -d --restart unless-stopped splunk/splunk:latest
sudo docker ps  # wait for it to say (healthy) then grab container ID
sudo docker stop $new_container

Then I restored it on the new server:

cd splunk_backup
sudo docker cp ./opt/splunk/ $new_container:/opt

Then I started the new server back up:

sudo docker start $new_container

As far as I can tell, all of my data, indices, users, reports, and dashboards were copied over successfully!
