Subject: Update from SmartThings Support ~ Hub Replace Feature
The following is the reply which I received from ST this morning. I consider this the final word on the subject.
The gist of the message is that there is not enough memory in the newest hubs to accommodate the the 95 devices that are on my v2 hub, which includes a few custom edge drivers and some virtual devices. My final device tally after eliminating all unnecessary devices and drivers is 95 devices, 20 which are virtual switches and a total of only 11 device drivers.
This is the outcome that I suspect we all anticipated. I will now post the response from ST Support followed my my reply to ST with a copy of the reply to Aeotec Support as well:
Thank you for your time and patience.
We have an update from our team I would like to inform you that the older V2 hub models support a higher level of memory resources than the Aeotec V3 models. If you have many different drivers, custom community built drivers, or virtual drivers these can cause an excess of memory resources being consumed on the source hub during a migration. When you attempt to start a hub replace migration you will see the error you are referring to.
We recommend cleaning out any unused drivers, and evaluating which custom/virtual drivers need to come over to the new hub. Once these have been removed to a sufficient level the migration will complete successfully.
If you still face any challenges please let us know.
The following is my reply:
Again, I am grateful to you and the SmartThings team for the research and assistance provided to me. I suspected this outcome because I am fully aware of the memory and processor downgrades that occurred in the v3 2018 SmartThings hub and the Aeotec hub, which is essentially a rebranded v3 ST hub.
I know that Samsung sold the equipment rights to Aeotec and that there is no intent on Samsung’s part to change the current hardware in the Aeotec hub. What confounds me, however, is why SmartThings made the decision to downgrade the hardware in the v3 hub. This makes no sense, particularly when memory continues to get less expensive and the advances in technology are getting increasingly complex, requiring more data resources.
I realize that it is now the responsibility of Aeotec to upgrade the hardware, which I think is critical to keep the SmartThings platform viable for the foreseeable future. As an influencer, I have maintained a strong loyalty to the SmartThings brand insisting that it is the sole smart home automation solution with the power and flexibility to seamlessly integrate all devices, eliminating the necessity for additional apps for non-native devices. However, considering the age of my 2015 v2 hub, the depreciation of the newest hardware, and the apparent lack of interest in developing a more capable hub, it may be time for me to consider other home automation solutions.
