Well, it served me well, and over the course of it's life it yielded me over 8 Billion ISK, with over 2 Billion ISK alone from it's current resting place: J161138
After 4 days of searching adjoining systems for a decent location to move the POS, I was growing weary of continually burning fuel and basically burning hours. With static exits to a Class 6 and NullSec only, and with my target being a Class 3 or 4, I decided it was time to jump out at the next convenient exit. I had been "chaining" exit WH's via the Class 6 but could not find the right fit - always led to more NullSec, C5, or C6 systems.
A HighSec exit (only the 3rd one ever here) opened and I jumped all over it, moving all of my ships, fittings, ammo, Refinery, 10 artillery, and all of my fuel stock to the exit system station.
With only 750M Mass allowance, it did not take long to go critically unstable, so I did not get most of the POS defenses unanchored before I had to make the final decision to abandon what remained. I could have stayed in there with my CovOps and continued waiting out the next High/LowSec exit to move the rest, but then I considered the total value of everything remaining (about 90M ISK in defenses + the Medium POS resale value at 180M ISK) and thought... "Well, you have cleared many Billions of ISK and you are moving up to a Large POS, so do you really need to put another 8 hours of offlining, unanchoring and transporting the Medium POS?" The answer, in short, was NO!
Remember, you have to offline and unanchor every unit before you can pack up that pricey POS, and with all of the stuff I had anchored out there, I shivered at the prospect of the mind-numbing effort of unanchoring everything in sequence. Here is what I left behind:
Shocked? Heheheh - tough decision, but once I took that last exit and bid my farewell to Apeiron, I felt like a weight lifted...
On to new horizons and new experiences with the Class 3/4 Large POS plan!
P.S. If someone comes across my old humble abode, please drop me a line - it served me well!
