上で|うえで

1. 1After first doing X, and on the basis of it, do Y.Ex. 1
2. 2After consulting with or considering something, as a formal step before acting.Ex. 2
3. 3In doing X or for the purpose of X, usually with evaluations like 大切だ or 必要だ.

A fairly formal expression common in business, official instructions, contracts and polite requests. With the た-form or a noun, it stresses that the first action is a prerequisite for the second, unlike plain てから. With the dictionary form, it frames the context in which something matters.

• 上にN2上に adds information ('not only... but also...'), with both clauses evaluated in the same direction; it can attach to adjectives, and its sentence generally does not end with a request or the like. 上で instead means 'after doing... then...' or 'in the area of' and attaches to verbs or a noun + の, so the two cannot be swapped.
• てからN5The two overlap in expressing 'first... then...'. てから attaches to the て-form, simply states sequence in a neutral register, and can also mean 'ever since...'; 上で attaches to the た-form or a noun + の, stresses the first action as a necessary prerequisite for the second, and sounds more formal.
• 上はN2上は means 'now that... (it follows that)...,' with the second clause expressing obligation, determination, or advice — a different meaning from 上で's 'do after' or 'in the area of,' so the two cannot be swapped. With nouns it takes 「である上は」 rather than の, and its tone is more written/formal.
• において / におけるN3において attaches only to nouns and marks place, time, or field in a more formal/written register; it has none of 上で's 'finish one thing, then do another' sense. It is close to 上で's 'in the area of' meaning, but 上で can attach to a verb in dictionary form ('when doing something'), while において cannot attach to verbs.
• 末にN2末に likewise attaches to the た-form or a noun + の, but presents a result that finally emerges after twists and turns, often pairing with ついに; 上で stresses acting with the first item as a premise. Both 「検討した末に決めた」 and 「検討した上で決めた」 are correct — they simply differ in emphasis.
• に際してN2に際して marks the moment of major occasions such as holding a meeting or graduating, does not attach to the た-form, and sounds more solemn. 上で, by contrast, either means 'after finishing the first action, do the second' or refers to the aspect involved in doing something, and it works for everyday matters, so the two generally cannot be swapped.

Unlike てから (simple sequence) and 末に (the outcome after a long process), 上で marks the first action as a deliberate basis for the next; 上に means 'on top of' and 上は means 'now that / since'. において marks a setting or field, and に際して means 'on the occasion of', neither implying a prerequisite step.
