Grant, I wish you well in adjusting to the move, and hope it will work out nicely for you. Deciding to make a career change involving a relocation can certainly be worrisome and will always involve some risk, both for us and for our families.
During my years in IT, I held positions in eight different companies in two different states but only HAD to relocate once, which I suppose is unusual. Except for the one job, all were located within easy driving distance of my home. Other times I changed my residence only by choice for upgrading. But the changes can be quite complicated and disrupting regardless of distance.
Having the luxury of 'defining the steps' does indeed make things much easier. Things such as a spouse's job, children's schools, distance from an employer location, and the like also can be selected and planned.
Maybe the relocation is easier for those of us who are already accustomed to anticipating and planning logical processes. My wife and I have relocated twice since our retirement, first state-to-state to be closer to family and return to reunite with old friends after being away 28 years, then a second time just about ten miles to take advantage of a son wanting us directly across the street from him. In both of these cases, we were at least able to take our time, plan things carefully, make proper arrangements ahead, and make the relocation in steps doing lots of it ourselves at a slow pace.
During the state-to-state relocation I spent a couple months living in a motel and commuting 150 miles on weekends to be with the family and do preparation.
Similar to both of our lives in technology, we proceeded through steps of first simplifying and cleaning up the current situation, preparing for the move in anticipation of an orderly process of arrival at the new digs. In our latest adventure, we even did most of the move of small items ourselves and placed them in the lower level of the new home in orderly fashion, then had movers do the large items. This allowed the inevitable remodeling and maintenance followed by a casual and orderly distribution of smaller items to their appropriate places on our relaxed schedule.
it is amazing how much 'overhead' is accumulated during many years, just like our systems at work. And there's a pun there. One of the tasks was removing many items from a large attic that had not been used in the duration of the residency there. Like the Lone Ranger theme song, 'To the Dump, To the Dump, to the Dump, Dump, Dump."
One of the best days of my IT career was they day I told my boss if the problem was so simple he should go fix it himself.
