5.2. Migrating Backups from Acronis Storage Gateway 1.6 and 1.7 (NFS)ΒΆ
- Disable the firewall or explicitly open TCP port 44446 on the source Acronis Storage Gateway. - To disable the firewall, run - # systemctl stop firewalld 
- To open TCP port 44446 in the firewall, do the following: - Find out the zone where port 44445 is open: - # firewall-cmd --list-all-zones | grep active mix_eth0 (active) 
- Add the required port to the same zone: - # firewall-cmd --zone=mix_eth0 --permanent --add-port=44446/tcp # firewall-cmd --reload 
 
 
- In the management panel of the ABGW node, proceed to SERVICES > Acronis Backup Gateway > Nodes, select node(s) to run the gateway services on, and click Migrate. 
- Select the source storage version and click NEXT. 
- Specify the connection details for the source storage and click NEXT.   
- Provide the credentials for the cloud management portal of the Acronis Backup Cloud installation that the source storage is registered in and click NEXT. 
- If the source storage is registered in Acronis Backup Cloud under an IP address, you will see the DNS configuration screen. On it, click RE-REGISTER WITH DNS and specify the source storage DNS name (recommended, see above). Or, if you want to keep using the IP address, click PROCEED WITH IP. - Important - If you specified a DNS name, configure your DNS server according to the suggested example.
- Each time you change nodes in the Acronis Backup Gateway, adjust the DNS settings accordingly.
 
- Choose a destination storage type to create a gateway to: - local Acronis Storage cluster,
- external NFS, or
- public cloud.
 
- Make sure a network interface with the ABGW private role is selected in the drop-down list. The corresponding interfaces with the ABGW public role will be selected automatically. Click NEXT. - Note - If necessary, click the cogwheel icon and assign the required role(s) to network interfaces on the Network Configuration screen. 
- Configure the destination storage backend: - For a storage cluster, select the desired tier, failure domain, and redundancy mode. 
- For NFS, specify a hostname or IP address, an export name and path, and choose the NFS version.   
- For public cloud, select a public cloud provider, specify credentials, and the name of the folder (bucket, container). - Important - You must update Acronis Backup Agents to version 12.0.4492 (Windows/Mac) or 12.0.4470 (Linux). Otherwise agents’ attempts to place backups in the new storage backend will result in “Backup failed” errors.   
 - Click NEXT. 
- Review the source and destination storages and click START MIGRATION. 
Depending on data size, migration may take as long as several days.
