2. Architecture

Application URLs

* Wordpress http://wordpress-web.onpremsim.env/
* OFBiz ERP https://ofbiz-web.onpremsim.env:8443/...
* Username: admin
* Password: ofbiz


3. CloudEndure Account

* Register - https://console.cloudendure.com/#/reg...
* Confirm Email
* Console Login - https://console.cloudendure.com/

4. CloudEndure Project

* Create Security Credentials for CloudEndure on AWS

* Create Project on CloudEndure
* Supply AWS Credentials of CloudEndure user
* Replication Settings
- Migration Source - Other Infrastructure
- Migration Target - AWS US West (Oregon)
- Subnet where the Replication Servers will be launched - TargetPublic

5. CloudEndure Agent install

Servers

* wordpress-web | `wordpress-web.onpremsim.env`
* wordpress-db | `wordpress-db.onpremsim.env`
* ofbiz-web | `ofbiz-web.onpremsim.env`
* ofbiz-db | `ofbiz-db.onpremsim.env`

- SSH to each server (Putty)
- Steps from CloudEndure console: Download & Install

6. CloudEndure Blueprint

- Machine Type: `t3.medium`
- Subnet: `TargetPrivate`
- Security Groups: `TargetSecurityGroup` and `Default`
- Private IP address: Create New
- Public IP (ephemeral): No
- Disks: SSD - gp2

7. Migration & Cutover

- Launch Target Machines - Cutover Mode
- Shutdown source environment (app and db servers)
- From SSH/Putty `sudo shutdown -h now`
- Or from Bastion host command line
```bash
ssh [email protected] "sudo shutdown -h now"

ssh [email protected] "sudo shutdown -h now"

ssh [email protected] "sudo shutdown -h now"

ssh [email protected] "sudo shutdown -h now"
```

- Fetch IP addresses of Target servers
- From cloudshell / cli
```bash
aws ec2 describe-instances \
--filters "Name=tag:Name,Values=*onpremsim*" \
--query "Reservations[].Instances[].[InstanceId,State.Name,PrivateIpAddress,Tags[?Key=='Name'].Value]" \
--output yaml
```

Sample output
```yaml
- - i-08aee74f68263b931
- running
- 10.0.1.224
- - wordpress-web.onpremsim.env
- - i-084d0b14b2879cb62
- running
- 10.0.1.180
- - ofbiz-web.onpremsim.env
- - i-01d341c7d83bc79c2
- running
- 10.0.1.121
- - wordpress-db.onpremsim.env
- - i-00f5a40b00c48deeb
- running
- 10.0.1.216
- - ofbiz-db.onpremsim.env
```

- Update DNS on Target servers

```bash
ADDR=`hostname -I`
HOST=`hostname`
sudo touch /tmp/nsupdate.txt
sudo chmod 666 /tmp/nsupdate.txt
echo "server dns.onpremsim.env" > /tmp/nsupdate.txt
echo "update delete $HOST A" >> /tmp/nsupdate.txt
echo "update add $HOST 86400 A $ADDR" >> /tmp/nsupdate.txt
echo "update delete $HOST PTR" >>/tmp/nsupdate.txt
echo "update add $HOST 86400 PTR $ADDR" >> /tmp/nsupdate.txt
echo "send" >> tmp/nsupdate.txt
sudo nsupdate /tmp/nsupdate.txt
```

- Tip: As an alternative to using Putty tool and logging into each server separately, you can also issue these commands over SSH from commandline of the bastion host.


```bash
ssh user@ipaddress < commands.txt
```

- Alernatively

```bash
putty -ssh [email protected]
```
