I'm attempting to merge 8 x Spectrum 9.4 landscapes down to 3 x Spectrum 10.x landscapes using modelling gateway as specified in the docs.
Each of the landscapes I am attempting to merge from is teetering on the limit for 32 bit and each one has between 90k and 130k model count.
I have exported just the models, connections, port info, annotations and GCs from one of the 9.4 landscapes and have attempted to import into the new 10.x one. Problem is after 10 minutes of "import will continue if no new models activate in x minutes" the import moves on with a good chunk of the devices still not activated.
As those models aren't activated, the connectivity import part doesn't work orrectly and we end up with a bunch of models with no links between them where there should be. These are all primarily 3Com and Juniper devices and just manually running "discover connections" on each container doesn't model them properly as there's spanning tree and other things involved.
I'd like to give the import process a good 1/2 hr or more to ensure all models are activated before moving on to the next stage. It may not get all of them in perfectly even after that, but the number of missed links should be significantly lower.
The only other alternative I'd have is to let the import run as is, then devise some sort of script to parse the error log and then re-link the models via CLI (REST is a mystery to me!)
Does any one have any ideas how I can make this work with as few errors as possible?
