When you need to move a VM from one server to another I start by opening up the console and selecting export. It grabs the config files along with the disks in one go. You choose a spot on the drive that has plenty of space. Sometimes the process runs longer if the disks are huge. Make sure the VM sits powered off or it refuses to budge.
I often run into cases where you export during off hours so nothing interrupts the copy. The files land in a neat folder structure that you can zip up or ship elsewhere. You check the permissions on that folder right after because odd access rights block the next steps. Perhaps you test a small VM first to see how your setup behaves. Then you repeat the same steps on bigger ones without guessing.
But moving stuff around gets tricky when versions differ between hosts. You watch for any mismatch in the hardware specs that the export pulls. I tweak the settings manually in the new spot if the CPU count feels off. Also the network adapters might need a quick reconnect once you fire it up. You verify the guest tools load properly after the import finishes.
Importing feels straightforward once the folder sits ready. You point the tool at that directory and pick the type of bring in you want. I go for the copy option most times so the original stays untouched. You handle the ID conflicts by letting it generate fresh ones automatically. Or you keep the old ID if you plan to replace the source machine entirely.
The disks can throw curveballs if they use fixed sizes instead of dynamic. I expand the storage ahead of time to avoid running out during the restore. You monitor the progress bar and step away only after it hits complete. Perhaps you script a quick check to confirm the VM boots without errors. Then you adjust the memory allocation based on what the workload demands.
Running into snapshots during export surprises you sometimes. I flatten them beforehand to keep the package clean and simple. You avoid dragging along extra checkpoints that bloat the size. Also the export folder might sit on a slow drive so plan the path carefully. I copy it to faster storage before attempting any import on the target.
Permissions matter a ton when you deal with shared storage setups. You grant the right accounts access or the whole thing halts midway. I double check the ownership after the files transfer across machines. Perhaps you run into driver issues on the new host that require updates first. Then the VM comes online and you test basic connectivity right away.
Storage paths change often between servers so you edit those inside the settings post import. I redirect them to the local volumes that match your environment. You confirm the network switches connect without dropping packets. Also the integration services might need reinstall if the versions clash. I keep notes on common fixes for the next time a similar move pops up.
Handling large scale transfers teaches you to break them into batches. You export one or two at a time instead of everything together. I watch the CPU load during these operations to prevent host overload. Perhaps you compress the exported folder if you send it over the wire. Then you verify the checksums match on both ends before deleting the source.
