1. Disable High Availability (this will cause the Slave to do a Factory Reset).
2. Disconnect the Ethernet cables from the Slave'
3. Install the 64-bit version from ISO onto the former Slave.
4. Put an unencrypted backup on a USB memory stick, and then reboot the Slave with that in place.
5. Power down the 32-bit Master.
6. Connect the new 64-bit ASG to the network.
7. In order to have the new MAC addresses recognized, you almost-certainly will need to "bounce" the routers/switches connected directly to the ASG. Depending on your environment, this may include the last-hop router of your ISP.
8. Once you've confirmed that the 64-bit system is working correctly, disconnect the 32-bit system.
9. Enable High Availability on the new 64-bit master. Image the 32-bit ASG with the 64-bit system and then connect it back as it was before. The Master will take it over and make it its Slave.
and are you truly doing a contstant 5-10 megabits/sec? Right now judging by what i have seen the cpu load on your ASg is expected for what you are pushing through the unit.
You can minimize downtime by:
Before the maintenance window:1. Disable High Availability (this will cause the Slave to do a Factory Reset).
2. Disconnect the Ethernet cables from the Slave'
3. Install the 64-bit version from ISO onto the former Slave.
4. Put an unencrypted backup on a USB memory stick, and then reboot the Slave with that in place.
Maintenance Window:5. Power down the 32-bit Master.
6. Connect the new 64-bit ASG to the network.
7. In order to have the new MAC addresses recognized, you almost-certainly will need to "bounce" the routers/switches connected directly to the ASG. Depending on your environment, this may include the last-hop router of your ISP.
8. Once you've confirmed that the 64-bit system is working correctly, disconnect the 32-bit system.
Before proceeding with the final step, you may want to connect to the 32-bit system (with a separate switch or a crossover cable), run reports, copy off logs, etc. You also might want to give the new 64-bit system at least a day in production before:9. Enable High Availability on the new 64-bit master. Image the 32-bit ASG with the 64-bit system and then connect it back as it was before. The Master will take it over and make it its Slave.
Does anyone see anything I've left out?

PS If you only have Web Security and Mail Security, you really should be able to do with NAT rules. At least, you could run in bridged mode, and, if you're running Web Security in a Standard mode, you really only need to have a single interface connected to your internal network (plus, of course, the Sync interface for HA).
a solution with no downtime
. I think we could have had it down to a minute if we'd done a better job of coordinating with their ISP. If you have your own router between your ISP and the Astaro, then you probably can get closer to a minute.
